Exercise: Greeting, Depending on Time of Day

A greeting has to be composed automatically, based upon time of day and sex.

  • Use the input() function to prompt the user on stdin for three variables,

    • Name

    • Sex. Valid inputs are m (male) and f (female); both uppercase and lowercase characters are allowed. All other input leads to program termination (use sys.exit(1) for erroneous termination).

    • Hour of day. Valid inputs are number 0 through 23; all other input leads to program termination.

  • Depending on the hour of day, the greeting starts with

    • 0 - 9: “Good morning, “

    • 10 - 17: “Good day, “

    • 18 - 23: “Good evening, “

  • Depending on the sex, the greeting continues with “Mrs.” or “Mr.”.

  • Last comes the name.

  • Finally, the greeting is output on stdout

$ python greet.py
Name: Jörg
Sex: f
Hour of day: 22

Good evening, Mrs. Jörg
