Python String center()

Python String center() method

Python String center() method is used to center align the given string in the specified length, with specified fill character.

Consider that given string is in x.

x = "Hello World"

Then the return value of x.center(21) is

"     Hello World     "

Syntax of center() method

The syntax of String center() method in Python is given below.

string.center(length, character)

The center() method takes two parameters.

center() method returns a new string created using the given string and appending equal number of fill characters at the edges till the length of resulting string reaches the given length.

The original string is not modified in value, and remains the same.

Examples

1. Center given Python string to a length of 21

In the following program, we take a string in variable x, and center the string to a resulting length of 21 using String center() method. We shall store the center() returned value in result variable. And then print both the original string x and centered string result.

Since fill character (second argument) is not specified, single space shall be used as fill character.

x = "Hello World"
result = x.center(21)
print(f"Given string    : \"{x}\"")
print(f"Centered string : \"{result}\"")

Output

Given string    : "Hello World"
Centered string : "     Hello World     "

2. Center given Python string to a length of 21 with fill character hyphen

In the following program, we take a string in variable x, and center the string to a resulting length of 21 with fill character “-“ using String center() method.

x = "Hello World"
result = x.center(21, "-")
print(f"Given string    : \"{x}\"")
print(f"Centered string : \"{result}\"")

Output

Given string    : "Hello World"
Centered string : "-----Hello World-----"
