Python capitalize() Method: Complete Guide

In Python, the capitalize() function is a method of string objects that converts the first character of a string to uppercase and leaves the rest of the characters unchanged. More specifically, the capitalize() function capitalizes the first letter of the string while leaving the other letters unchanged.

Here is an example using the capitalize() function:

s = "hello world"
capitalized_s = s.capitalize()
print(capitalized_s)  # 输出 "Hello world"

In the example above, the original string “hello world” has been processed by the capitalize() function, where the first letter “h” is converted to uppercase “H”, while the other characters remain unchanged.

The capitalize() function is commonly used to format or standardize strings by ensuring that the first letter is capitalized, for example in user interfaces or text processing.
