The first step is to input data and then I want to check to make sure there are only digits and no other type of characters. I thought regex would be great for this. The program works great, but no matter what I enter, the regex part does the same thing. By same thing I mean this:
======== RESTART: C:\Users\Roger\Documents\GitHub\ciphers\cipher1.py ======== Please enter an integer less than 10,000 greater than 0: 4jkk33 No match >>> ======== RESTART: C:\Users\Roger\Documents\GitHub\ciphers\cipher1.py ======== Please enter an integer less than 10,000 greater than 0: 4k33 No match >>> ======== RESTART: C:\Users\Roger\Documents\GitHub\ciphers\cipher1.py ======== Please enter an integer less than 10,000 greater than 0: 4jjk4 No match >>> ======== RESTART: C:\Users\Roger\Documents\GitHub\ciphers\cipher1.py ======== Please enter an integer less than 10,000 greater than 0: 4334 No match So I don't know what I'm doing wrong. The cipher will still draw, but I want to return an "error message" in this case print("No match"), but it does it every time, even when there are only digits; that's not what I want. Please help. Below is my code: from turtle import * import re # use turtle to draw ciphers of the Cistercian monks digits = input("Please enter an integer less than 10,000 greater than 0: ") """ ensure input is no other characters than digits sudocode: if the input has anything other than digits return digits """ #def digit_check(digits): # I thought making it a function might h p = re.compile(r'[^\D]') m = p.match(digits) if m: print("No match") else: print(digits) digits = m #digit_check(digits) mode("logo") # resets turtle heading to north speed(0) ht() fd(100) # if statements for the ones position if digits[-1] == "1": pu() goto(0, 100) seth(90) pd() fd(35) if digits[-1] == "2": pu() goto(0, 65) seth(90) pd() fd(35) if digits[-1] == "3": pu() goto(0, 100) seth(135) pd() fd(50) if digits[-1] == "4": pu() goto(0, 65) seth(45) pd() fd(50) if digits[-1] == "5": pu() goto(0, 100) seth(90) pd() fd(35) rt(135) fd(50) if digits[-1] == "6": pu() goto(30, 100) seth(180) pd() fd(35) if digits[-1] == "7": pu() goto(0, 100) seth(90) pd() fd(35) rt(90) fd(35) if digits[-1] == "8": pu() goto(0, 65) seth(90) pd() fd(35) lt(90) fd(35) if digits[-1] == "9": pu() goto(0, 100) seth(90) pd() fd(35) rt(90) fd(35) rt(90) fd(35) # if statements for the tens position if digits[-2:-1] == "1": pu() goto(0, 100) seth(-90) pd() fd(35) if digits[-2:-1] == "2": pu() goto(0, 65) seth(-90) pd() fd(35) if digits[-2:-1] == "3": pu() goto(0, 100) seth(-135) pd() fd(50) if digits[-2:-1] == "4": pu() goto(0, 65) seth(-45) pd() fd(50) if digits[-2:-1] == "5": pu() goto(0, 100) seth(-90) pd() fd(35) lt(135) fd(50) if digits[-2:-1] == "6": pu() goto(-30, 100) seth(180) pd() fd(35) if digits[-2:-1] == "7": pu() goto(0, 100) seth(-90) pd() fd(35) lt(90) fd(35) if digits[-2:-1] == "8": pu() goto(0, 65) seth(-90) pd() fd(35) rt(90) fd(35) if digits[-2:-1] == "9": pu() goto(0, 100) seth(-90) pd() fd(35) lt(90) fd(35) lt(90) fd(35) # if statments for the hundreds position if digits[-3:-2] == "1": pu() goto(0, 0) seth(90) pd() fd(35) if digits[-3:-2] == "2": pu() goto(0, 35) seth(90) pd() fd(35) if digits[-3:-2] == "3": pu() goto(0, 0) seth(45) pd() fd(50) if digits[-3:-2] == "4": pu() goto(0, 35) seth(135) pd() fd(50) if digits[-3:-2] == "5": pu() goto(0, 0) seth(90) pd() fd(35) lt(135) fd(50) if digits[-3:-2] == "6": pu() goto(30, 0) seth(0) pd() fd(35) if digits[-3:-2] == "7": pu() goto(0, 0) seth(90) pd() fd(35) lt(90) fd(35) if digits[-3:-2] == "8": pu() goto(0, 35) seth(90) pd() fd(35) rt(90) fd(35) if digits[-3:-2] == "9": pu() goto(0, 0) seth(90) pd() fd(35) lt(90) fd(35) lt(90) fd(35) # if statments for the thousands position if digits[-4:-3] == "1": pu() goto(0, 0) seth(-90) pd() fd(35) if digits[-4:-3] == "2": pu() goto(0, 35) seth(-90) pd() fd(35) if digits[-4:-3] == "3": pu() goto(0, 0) seth(-35) pd() fd(50) if digits[-4:-3] == "4": pu() goto(0, 35) seth(-135) pd() fd(50) if digits[-4:-3] == "5": pu() goto(0, 0) seth(-90) pd() fd(35) rt(135) fd(50) if digits[-4:-3] == "6": pu() goto(-30, 0) seth(0) pd() fd(35) if digits[-4:-3] == "7": pu() goto(0, 0) seth(-90) pd() fd(35) rt(90) fd(35) if digits[-4:-3] == "8": pu() goto(0, 35) seth(-90) pd() fd(35) lt(90) fd(35) if digits[-4:-3] == "9": pu() goto(0, 0) seth(-90) pd() fd(35) rt(90) fd(35) rt(90) fd(35) <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
