What is the method for checking for an empty string in Python?

In Python, you can use the following method to check if a string is empty:

1. if that’s the case

string = ""
if len(string) == 0:
    print("字符串为空")

1. I do not want to go.
2. Convert to a boolean.

string = ""
if not bool(string):
    print("字符串为空")

1. if

string = ""
if string is None or string == "":
    print("字符串为空")

Please note that the above method is used to determine if a string is empty. If you want to check if a string only contains spaces or special characters, you can use the strip() method of the string or regular expressions for verification.
