Read N Lines and Edge Cases
Loop over lines and handle trailing whitespace.
The N-Then-Lines Pattern
A classic input format gives a count N first, then N lines of data. Read the count, then loop exactly N times.
Read the Count First
Pull the first line and turn it into an integer with int(). That number controls how many more lines you read.
