Exercise 5: Display numbers from a list using loop. If there is a while loop in python with a break statement and an else statement, the else statement skips when the"break" executes. Map in Python : Map is used to compute a function for different values ‘in a single line of code ‘ . It’s similar to an “if-else” statement and the only difference is that in “else” we will not check the condition but in “elif” we will check the condition. It's just on the boundary of being unreadable, which is often a tradeoff with ternary operators and single-line loops. If the condition evaluates to True, then Python executes the body of the while-loop. But let’s then take a look at what happens when you turn it into a one-liner expression: result = x * 2 + 10 if x % 2 == 0 else x / 2 - 10. result = x * 2 + 10 if x % 2 == 0 else x / 2 - 10. You don't. In part 1 we learned what Jinja2 is, what are its uses, and we started looking at templating basics.
