Python3.x Python3 center() Method

Python3 Strings

The center() method returns a centered string of a specified width, using a specified fill character (default is a space).

Syntax

Syntax for the center() method:

str.center(width[, fillchar])

Parameters

width -- The total width of the string.
fillchar -- The fill character.

Return Value

Returns a centered string of the specified width. If the width is less than the string's width, the original string is returned directly; otherwise, it is padded with the fill character.

Examples

The following examples demonstrate the use of the center() method:

Example

#!/usr/bin/python3

str=""

print("str.center(40, '*') : ",str.center(40,'*'))

The output of the above example is as follows:

str.center(40, '*') : ********************************

str.center(width[, fillchar]) function:

If the width is less than the string's width, the original string is returned directly without truncation:

>>> str = "[www.]"
>>> print ("str.center(4, '*') : ", str.center(4, '*'))
str.center(4, '*') : [www.]  # width is less than the string width

fillchar defaults to a space:

>>> str = "[www.]"
>>> print ("str.center(40) : ", str.center(40))
str.center(40) : [www.]  # fillchar defaults to a space

fillchar must be a single character:

>>> str = "[www.]"
>>> print ("str.center(40, '?!') : ", str.center(40, '?!'))
Traceback (most recent call last):
  File "", line 1, in 
TypeError: The fill character must be exactly one character long
