What does the python ipo model refer to?

IPO (Input Processing Output) mode, that is, input data → process data → output results. For example:

# month.py
months="JanFebMarAprMayJunJulAugSepOctNovDec"
n=input("请输入月份数（1-12）：")
tran=(int(n)-1)*3
monthAbbrev=months[tran:tran+3]
print("月份简写是："+monthAbbrev+".")

Note: The input content is in string format. If the input is a numerical value, instructions such as int(), float() and complex() should be used to convert the input value (string type) is a numeric type.

If you want to directly get the input value of numeric type, you can use the eval_r() function to get the input result return value.
