How to remove the last element in a Python list?

You can use slicing to remove the last character. Slicing allows you to extract a portion of a string and return a new string. To remove the last character, you can set the slice range of the string from the beginning to the second-to-last character. Here’s an example:

s = "Hello World"
new_s = s[:-1]
print(new_s)  # 输出: Hello Worl

In this example, [:-1] represents a slice range from the beginning to the second to last character.
