I want to know whether some string is in same string or not (yeah the SAME) 
in the file attached I have two expressions:
1- print('اندیمشک' in 'اندیمشک')
2- print('اندیمشک' in 'اندیمشک')
as you can see both of them are same thing but if you run the program you see it returns True for first one and False for second one. the difference between two expressions is that in the first one I typed both of the strings but in the second one I copied second string from a file and type first string

Thanks
