How do you convert string to lowercase in Python?

In Python, you can convert strings to lowercase using the lower() method of the string. This is a straightforward and commonly used method that doesn't require additional imports or complex operations.

For example, if you have a string "Hello World" and you want to convert it to all lowercase, you can use the following code:

python
original_string = "Hello World"
lowercase_string = original_string.lower()
print(lowercase_string)

The output will be:

shell
hello world

This method is highly effective regardless of the original string's character composition, such as containing uppercase letters, numbers, or special symbols. The lower() method converts all uppercase English letters to lowercase English letters while leaving other characters unchanged. This is particularly useful for data processing and text analysis, such as when performing text comparisons where case sensitivity is often ignored.
