Understanding Python's strip() Method and Example Usage

The article introduces the Python strip() method, which removes leading and trailing characters (defaulting to whitespace) from a string, and notes that it cannot delete characters from the middle of the string.

while(True):</code><code>      问话=input("真人:");</code><code>      print("假机器人:"+问话.strip("吗??")+"!");

It then describes the method signature str.strip([chars]), where the optional chars argument specifies the set of characters to be removed, and mentions that the method returns a new string with the characters stripped.

str = "123abcrunoob321"</code><code>print (str.strip( '12' ))  # characters sequence 12

The example outputs the result:

3abcrunoob3
