Lines And Their Lengths

Three lines read from input are written to lengths.txt and the file is then read back with a loop that is already in place. Inside it, remove the newline from the line with rstrip and print the line, a colon, a space and the line's length, one per line in file order. Input: three lines, no prompt.

Expected Output:

cat: 3↵
house: 5↵
hi: 2↵

= newline. The output ends with a newline — print one after the last line.
