[SOLVED] My python3 script not doing what I want it to do

jackx2023 · 04-01-2023, 02:12 AM

I am very new to python. I was testing my little knowledge of python by creating a simple for/if loop.

Here is my code

Code:

#!/usr/bin/python3                         
matched =[]
count = 0
win_nums = ('1','15','20','31','50')

mynums = input("Enter your numbers: ")

for i in mynums:
     if i in win_nums:
         count += 1
         matched.append(i)

print (f"you mantch {count} numbers. They are {matched}")

When I run it, I get this below

Code:

./lottocheck.py
Enter your numbers: 1 17 25 31 51
you mantch 4 numbers. They are ['1', '1', '1', '1']

It should have given me 1 and 31 with 2 matches.

I tried changing the line from if i in win_nums: to if i == win_nums: and I get

Code:

./lottocheck.py 
Enter your numbers: 1 17 25 31 51
you mantch 0 numbers. They are []

Any ideas what I am doing wrong. I appreciate any help. Thanks

first I would try to add some print statements to see what's going on:

Code:

#!/usr/bin/python3                         
matched =[]
count = 0
win_nums = ('1','15','20','31','50')

mynums = input("Enter your numbers: ")

for i in mynums:
     print(i)                   # like this
     if i in win_nums:
         count += 1
         matched.append(i)

print (f"you mantch {count} numbers. They are {matched}")

@ pan64

The fix was simple. I needed to use the split() function for the mynums arrary. Like so:

for i in mynums.split():

Now when I run it

Code:

/lottocheck.py 
Enter your numbers: 20 31 50 77 99
you mantch 3 numbers. They are ['20', '31', '50']

./lottocheck.py 
Enter your numbers: 1 15 20 31 50
you mantch 5 numbers. They are ['1', '15', '20', '31', '50']


The hard thing about python is remembering the string function and modules. lol :)

that is great. In that case you might want to mark the thread as solved.
