pythonstring

In Python, how do I create a string of n characters in one line of code?

I need to generate a string with n characters in Python. Is there a one line answer to achieve this with the existing Python library? For instance, I need a string of 10 letters:

string_val = 'abcdefghij'
Solution

  • To simply repeat the same letter 10 times:

    string_val = "x" * 10  # gives you "xxxxxxxxxx"

    And if you want something more complex, like n random lowercase letters, it's still only one line of code (not counting the import statements and defining n):

    from random import choice
from string import ascii_lowercase
n = 10

string_val = "".join(choice(ascii_lowercase) for i in range(n))
