For example, I get a string:
str = "please answer my question"
I want to write it to a file.
But I need to know the size of the string before writing the string to the file. What function can I use to calculate the size of the string?

If you are talking about the length of the string, you can use len():
>>> s = 'please answer my question'
>>> len(s) # number of characters in s
25
If you need the size of the string in bytes, you need sys.getsizeof():
>>> import sys
>>> sys.getsizeof(s)
58
Also, don't call your string variable str. It shadows the built-in str() function.
