Print the longest str from user input

[perfringo]

As stated - this is only Python 3.8 compatible code (using walrus operator).

Task can be described: 'collect user input until break and find longest input'

So

# assign empty list to a name where user input will be collected

# while True loop - executes until 'break' encountered in the body of loop
# assign name to user input
# check if user input is break symbol or word, if so - break loop
# append answer to list of collected inputs

# print max value by length in list
