Facebook: a large number of basic libraries are implemented in Python
RedHat: the most popular Yum package management tool in the world's new version of Linux is developed in Python
② crawler:
now is the era of big data, and crawler belongs to a more operational scenario. For example, Google crawler was written in Python in its early stage, If you are interested in collecting and processing data, crawler engineers will be a good choice
③ data analysis:
generally, after we use crawlers to crawl a large amount of data, we need to process the data for analysis, otherwise the crawler will crawl in vain, and our ultimate goal is to analyze the data. In this regard, the database of data analysis is also very rich, and all kinds of graphic analysis charts can be made. It is also very convenient. Visual libraries such as Seaborn can plot data with only one or two lines, while pandas, numpy and SciPy can simply filter and regress a large number of data< (4) Artificial Intelligence:
the main reason why Python is well known in recent years is the rise of artificial intelligence
Python has a good reputation in the field of scientific computing. Its concise and clear syntax and rich computing tools are loved by developers in this field
Python has the characteristics of simple writing and few changes. Especially suitable for machine learning. And provides a rich library. It reces the cost of learning artificial intelligence.

On April 15, the dog coin rose 50%; On April 16, it soared again, with an increase of 250% in 24 hours, reaching a maximum of US $0.47 per piece, and its total market value once exceeded US $60 billion

Recently, with the rise of many virtual currencies, the time for bitcoin to rise from more than 1000 yuan to 10000 yuan should be longer than that for dogcoin to rise from 1 Li to 10 cents. If we look at the cost of digging dogcoin in two months, it will be halved. That is to say, with the same computing power, the cost of digging dogcoin will double in two months, It is the key to the survival of a currency, and the emergence of Dog Coin miner is the biggest support for dog coin's computing power. If the computing power doubles, the cost of digging money will also double. The cost of digging money is the support point of the price, so I can only think that it is not impossible to break through one dollar

In February 2014, Mt. GOx, once the number one bitcoin exchange in the world, was stolen about 850000 bitcoins by hackers, resulting in its final bankruptcy. Until now, Mt. GOx's traders have not been compensated. In a year and a half, it has been hacked three times, which is a wonderful work in the instry. It deeply reflects that there are loopholes in the security of the coin security platform that can not be ignored. Coin security has also been jokingly called "hacker ATM"

Maybe he thinks that the national regulatory policies are irrelevant. After returning to China, he quickly launched futures trading, IEO financing and other businesses, and made high-profile publicity on social media to gather investors without scruple. The currency has opened a French currency trading area to guide users to buy digital currencies such as WeChat, Alipay and bank cards, and to conct transactions between digital currency and RMB. This is a serious challenge to the bottom line of regulation. This is not only a war between Alipay and currency, but also a battle between regulation and currency security. How far can an enterprise that disrupt the normal market order go? So we are looking forward to Alipay's success. strong>

6. The audit procere of Monetary Fund

monetary fund is a required manuscript for new comrades. My first draft is monetary capital, but it's ridiculous that I didn't carry out any audit proceres, because the cash on the enterprise's account is more than 600000 yuan, and it's distributed all over Jiangsu Province, so I have no choice but to take the lead and let it go first

although monetary fund is the patent of new people, it is an important field in audit work. The continuous change of account balance may result from almost all aspects of customers' business, such as sales collection, purchase of inventory and fixed assets, payment of wages and other expenses, etc. At the first audit, I couldn't figure out how to hand over such an important subject to me casually. Later, I graally understood that just as there is a loan in accounting, auditing can be carried out from both sides. Most of the original tests related to cash and bank deposit systems were included in the "sales and collection cycle" and "purchase and payment cycle". Since that is the case, is there nothing to do with the audit of monetary funds? In fact, it is not true that although the audit of monetary funds has no technical content, it requires considerable patience, care and physical strength How can I be sure of my work Next, I'll talk about the general situation of Monetary Fund Audit in combination with the audit books I read and the audit assistant guide of Ernst & young

before examining the monetary fund, we should first understand the business situation of the enterprise, so as to better analyze the rationality of the enterprise accounting. The following aspects should be considered:

1. How many bank accounts does the customer have, and what are the purposes of each account

2. What kind of cash do customers have, where do they keep it, and what are their purposes

3. What are the main collection methods for customers, such as cash sales collection, telegraphic transfer collection, check collection, etc., and what kind of business do they correspond to

4. What are the main payment methods for customers, such as cash payment, telegraphic transfer payment, check payment, etc., and what kind of purchase and payment do they correspond to

after understanding the general situation of enterprise operation, we can start to implement the audit proceres. There are no more than two kinds of proceres: control test procere and substantive procere

control test procere - the main control is the review and sample re compilation of the customer's regular bank balance reconciliation table

internal control test content:

1. For collection, the money collected by the enterprise must be received by the enterprise and recorded in time, and should not be collected into the wallet of other people / companies

2. Payment, all payments can only be paid with the authorization of at least two people, and timely and correct accounting<

substantive proceres – our substantive work in the area of bank balance reconciliation includes checking the reconciliation statement and checking the reconciliation items to supporting documents, especially those near the end of the period. Other substantive proceres include obtaining bank confirmations and checking bank accounts for unusual or unexpected items<

substantive test content:

1. Details of cash and bank deposits obtained

2. Obtain all bank statements at the end of the period, and then write to all bank accounts

3

4. Review the bank deposit balance adjustment tables of all bank accounts. For the adjustment items, consider the reasons and whether to make adjustments

5. It is better to make audit adjustment for large amount of adjustment items, especially for the enterprises that have adjusted items for a long time and have received but not received by the bank, and for the enterprises that have paid but not paid by the bank

6. If there are a lot of deposits, is there a problem in the use of funds? Should I repay the loan

7. Compared with last year, are there frequent changes in bank accounts

8. Whether there are restricted funds in bank accounts, such as pledged bank deposit slip and bank deposit used as margin

9. Distinguish the maturity of bank deposits, and consider adjusting the currency with a maturity of more than 3 months

10

11. Spot check the large amount of withdrawal and payment on the enterprise bill to see if it is reasonable

e to the wide range involved, the audit of monetary funds should focus on the control test.

7. 1、 The objectives of cash audit are as follows:
(1) to determine whether the cash of the audited entity is real on the balance sheet date
(2) whether the revenues and expenditures occurred ring the trial period are true and legal, and whether the records are complete< (2) important substantive testing proceres:
1. Checking cash on hand:
checking cash on hand is an important procere to verify the existence of cash listed in the balance sheet
the cashier and accountant in charge of the audited unit must participate in the inventory, and the certified public accountant must participate in the inventory supervision
generally, a surprise inspection should be carried out before work in the morning or after work in the afternoon. The scope of the inventory generally includes the cash managed by various departments of the enterprise
make an inventory of the cash in the safe and prepare & quot; Cash on hand inventory & quot
when counting after the balance sheet date, the amount should be adjusted to the balance sheet date
check the counting amount with the balance of cash journal. If there is any difference, find out the reason and make record or appropriate adjustment.

8. It has been proved that the central bank has never issued the so-called bank of China currency...... if anyone wantonly spreads the propaganda of infringing the central bank and swindles investors, he will be investigated for criminal responsibility with the weapon of Law
