You can do it simpler: s = "Hi, friend" hidden = s[0] + '*' * (len(s) - 2) + s[len(s) - 1] print(hidden) But length of a string should be at least 2 characters

Use a range.

Use the enumerate function inside the join. It will give you the index of each letter too. Then you can compare this index with the string length in the ternary expression.

Answer is: func = lambda x = 'hi, Fri': ''.join(x[c] if x[c] in '' for c in (0, len(x)-1) else '*' for c in range(len(x))) print(func()) Thanks for all a lot!

the first index is 0 the last index is -1 or the length-1 (of the string)

Just use slicing.Copy the string into a temp=string[1:len (string)-1] and perform the operation

But what if I want to complicate this task and to replace uppercase symbols, therefore I need to use a cycle and the isupper() method to get @***@***** from string 'Hi, Friend', or how?

mystring = "Hi, Friend" for x in range(1, len(mystring)-1): mystring = mystring.replace(mystring[x], '*') print(mystring)

Sousou, It works! But we need to replace also all spaces and punctuation marks. Expected: Hi, Friend => H********d
