Python String center() Method

Last Updated : 30 Dec, 2024

center() method in Python is a simple and efficient way to center-align strings within a given width. By default, it uses spaces to fill the extra space but can also be customized to use any character we want.

Example:

# Center the string 'hello' within a width of 20
s1 = "hello"
s2 = s1.center(20)

# Print the result
print(s2)

Output

       hello

Table of Content

Syntax
Using fillchar Parameter

Example: Handling Width Smaller than String Length
Example: Creating Header for Table

Syntax

string.center(length[, fillchar])

Parameters

length: length of the string after padding with the characters.
fillchar: (optional) characters which need to be padded. If it’s not provided, space is taken as the default argument.

Returns

Returns a string padded with specified fillchar and it doesn’t modify the original string.

Using fillchar Parameter

The center() method also allows us to specify a character to fill the empty spaces instead of spaces. This can be useful if we want to use another symbol like a dash (-) or an asterisk (*) for alignment.

# Center the string 'hello' with dashes
a = "hello"
b = a.center(20, '-')

# Print the result
print(b)

Output

-------hello--------

Example: Handling Width Smaller than String Length

If the width specified in the center() method is smaller than the length of the original string, Python will not change the string. It will simply return the original string without any centering.

# String 'hello' with width 3 (smaller than the length of the string)
a = "hello"
b = a.center(3)

# Print the result
print(b)

Output

hello

Example: Creating Header for Table

When printing a table or a list of data, we might want to center-align the headers to make them stand out. This is a common use case for the center() method.

# Table headers
h1 = "Name"
h2 = "Age"
h3 = "Location"

# Center each header within a width of 20 characters
s1 = h1.center(20, '-')
s2 = h2.center(20, '-')
s3 = h3.center(20, '-')

# Print the headers
print(s1)
print(s2)
print(s3)

Output

--------Name--------
--------Age---------
------Location------

Here, the headers are centered and the extra space is filled with dashes (-). This gives the headers a clean and organized look when printed.
