USE Python

1. Assign value 555 to the variable x, write code to square the variable x and print out the result.

2. Given a string x, write a program to check if its first character is the same as its last character. If yes, the code should output "True" .

3. We defined two variables, x = 'Python' and y = '3.0'. Write code to concatenate the two numbers (the result should be 'Python3.0').
