Given num_rows and num_cols, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print
a space after each seat, including after the last. Ex: num_rows = 2 and num_cols = 3 prints: 1A 1B 1C 2A 2B 2C num_rows = 2
num_cols = 3
# Note 1: You will need to declare more variables
# Note 2: Place end=' ' at the end of your print statement to separate seats by spaces
