More methods are discussed in this article
1. strip():- This method is used to delete all the leading and trailing characters mentioned in its argument.
2. lstrip():- This method is used to delete all the leading characters mentioned in its argument.
3. rstrip():- This method is used to delete all the trailing characters mentioned in its argument.
 

Output: 
 

 String after stripping all '-' is : geeksforgeeks
 String after stripping all leading '-' is : geeksforgeeks---
 String after stripping all trailing '-' is : ---geeksforgeeks

4. min("string"):- This function returns the minimum value alphabet from the string.
5. max("string") :- This function returns the maximum value alphabet from string.
 

Output: 
 

The minimum value character is : e
The maximum value character is : s

6. maketrans():- It is used to map the contents of string 1 with string 2 with respective indices to be translated later using translate(). 
7. translate():- This is used to swap the string elements mapped with the help of maketrans().
 

Output: 
 

The string after translation using mapped elements is : 
aeeksbcraeeks

In the above code, 'g' is replaced by a, 'f' is replaced by b, and 'o' is replaced by 'c' in the string using the translate function.
8.replace():- This function is used to replace the substring with a new substring in the string. This function has 3 arguments. The string to replace, new string which would replace and max value denoting the limit to replace action ( by default unlimited ). 
 

Output: 
 

The string after replacing strings is : geeksforgeeks is for nerds
