We are accepting the string being passed tostr.format()in the index position of 0 since we did not specify otherwise, including the colon, and specifying that we will use*instead of space to fill up the field. We’re centering the string with^, specifying that the field is 20 characters...
You can use the built-ineval()to evaluate arbitrary Python expressions from string-based or compiled-code-based input. This is a good option if you need to dynamically evaluate Python expressions. When you pass a string argument toeval(), it compiles it into bytecode and evaluates it as a...

This is not an in-place modification, so the original String gets not changed.Use reversed()¶Another option (but slower) is to combine str.join() and reversed():my_string = "Python" reversed_string = ''.join(reversed(my_string)) print(reversed_string) # nohtyP print(reversed(my_...
mind that each character is case-sensitive. If we want to search for all the letters in a string regardless of case, we can use thestr.lower()method to convert the string to all lower-case first. You can read more about this method in “An Introduction to String Methods in Python 3....
