How to find the size of a string in Python

Question

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?

Answer 1

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 str. It shadows the built-in str() function.

Hope this would help you @bug_seeker

Answer 2

following way to find length of string 

x = input("Enter a string:")
counter = 0 # count the character in string 
for s in x:
      counter = counter+1
print("Length of the input string is:", counter)

output

Enter a string: rajesh

Length of the input string is:6

i want to say somethings string is very important in python so if you know more about python and string concept in python than you can join
