The string.lower() function receives a string and returns a transformed copy with all uppercase letters changed to lowercase, and all other characters unchanged. Uppercase characters are defined by the current locale.

Syntax

string.lower( s )

Where s is a string.

Returns a copy of s with letters that are uppercase in the current locale converted to lowercase. The string s is unmodified.

Example

The code below demonstrates a basic implementation of the string.lower() function.

stringvar = string.lower("HOw Now Brown CoW?")
print(stringvar)

This will result in the following output:

how now brown cow?
