[Tutor] failed to load functions,

[lina]

Hi,

sorry for the new post:

if __name__=="__main__":

    for i in range(97,100):
        for j in range(97,100):
            if i != j:
                s1=chr(i)+"List"
                s2=chr(j)+"List"
                '''print(s1,s2)'''
                LongestCommonSubstring(s1,s2)

I am surprised the results showed like below:

$ python3 CommonSubstring.py
Lis
List
Lis
List
Lis
List
Lis
List
Lis
List
Lis
List

and
                print(s1,s2)
                '''LongestCommonSubstring(s1,s2)'''
showed me:

aList bList
aList cList
bList aList
bList cList
cList aList
cList bList


exactly I wanted,

but seems s1, s2 failed to go into functions.

Thanks,
