Use the `str.count()` method to check if a character appears twice in a string, e.g. `if my_str.count(char) == 2:`.
# Check if the string ends with "world!" if my_string.endswith("aboard!"): print("The string ends with 'aboard!'") else: print("The string does not end with 'aboard!'") Output The string ends with 'aboard!' Example In this example, we define a list of suffixes and a string...

In JavaScript, there is no built-in function to check if every character in a given string is in uppercase format or not. So, we have to implement our function. Here, we will create a function calledisUpperCase(), an anonymous arrow function, to tell us whether all the characters in a...
foo2([4,10,True], "g") # OK: list is acceptable in place of tuple foo2((4,10,1), "rg") # Wrong: 1 is not a bool, string is too long foo2(None, "R") # Wrong: None is no tuple, string has illegal character 1. ...
