How to get the size of a string in Python? -

for example, string:

str = "please answer question" 

i want write file.

but need know size of string before writing string file. function can use calculate size of string?

if talking length of string, can use len():

>>> s = 'please answer question' >>> len(s)  # number of characters in s 25 

if need size of string in bytes, need sys.getsizeof():

>>> import sys >>> sys.getsizeof(s) 58 

also, don't call string str. shadows built-in str() function.
