Question

Write a function num_day that takes a number in the range of 1 through 7 as a parameter and
returns a string representing the corresponding day of the week, where 1=Monday, 2 =Tuesday,
3=Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday, and 7 = Sunday. The function should return
the string "Error" if the parameter is that is outside the range of 1 through 7. You may assume
that the parameter will be only numbers. Save the function in a PyDev library module named
functions.py
Write a testing program named t02.py that tests the function by asking the user to enter a number
and displaying the output.
A sample run:
Please enter a number between 1 and 7: 7
The number 7 corresponds to Sunday.

Answer 1

Source Code:

functions.py (module)

def num_day(n):
   if(n<1 or n>7):
       return "Error"
   else:
       if(n==1):
           return "Monday"
       elif(n==2):
           return "Tuesday"
       elif(n==3):
           return "Wednesday"
       elif(n==4):
           return "Thursday"
       elif(n==5):
           return "Friday"
       elif(n==6):
           return "Saturday"
       elif(n==7):
           return "Sunday"

t02.py (main file)

import functions # importing functions.py module file

num=int(input("Please enter a number between 1 and 7:"))
print("The number",num,"corresponds to",functions.num_day(num))
