How do I verify if the sudokus lines do have all 9 digits?

Question

Could someone please give me advice of how to start my code? I am supposed to verify if a text document containing rows of 9 numbers do have all 9 digits. If so, my code should say True, otherwise False.

Here is one of the text document examples

5,3,4,2,7,6,9,1,8
6,2,8,1,9,5,3,4,7
1,7,9,3,4,8,5,6,2
8,5,2,7,6,1,4,9,3
4,9,6,8,5,3,7,2,1
7,1,3,9,2,4,8,5,6
9,6,1,5,3,7,2,8,4
2,8,6,5,1,9,6,3,5
3,4,5,6,8,2,1,7,9

Code must say False Thank you very much

because at the 8th line, there is two 3 and two 5, so there is not all 9 digits — Michelle, Oct 21 '18 at 17:10

You could do something like this (ofcourse you need to read from file and that's left to you):

s = '''5,3,4,2,7,6,9,1,8
6,2,8,1,9,5,3,4,7
1,7,9,3,4,8,5,6,2
8,5,2,7,6,1,4,9,3
4,9,6,8,5,3,7,2,1
7,1,3,9,2,4,8,5,6
9,6,1,5,3,7,2,8,4
2,8,6,5,1,9,6,3,5
3,4,5,6,8,2,1,7,9'''

for x in s.split('\n'):
    print(''.join(sorted(x.split(','))) == '123456789')

# True
# True                                                        
# True                                                        
# True                                                        
# True                                                        
# True                                                        
# True                                                       
# False                                                       
# True

This checks whether each line contains all numbers from 1 to 9 in any order, giving out a True in that case else a False.
