Question

I want to know how can we read multiple input like [“a”,”b”,”c”] and store it in same variable. I want to store a , b ,c as a separate input to a variable.
thanx

Answer 1

If you are actually getting input from stdin or from a file, then it is as easy as using the split() function

f=open( 'myfile.txt', 'r')
for line in f.readlines():
    # suppose line is '["a","b","c"]'
    a = line.split( ',' )
    # a is now the list [ '["a"', '"b"', '"c"]' ]

    # To strip away the brackets use this instead:
    a = line.strip('[]').split( '[]' )
    # a is now the list [ '"a"', '"b"', '"c"' ]

    # To strip away the spurious quote marks use this instead:
    a = [ s.strip('"') for s in line.strip('[]').split(',') ]
    # a is now the list [ 'a', 'b', 'c' ]

Of course, you could roll this into a single list comprehension:

lines = [ s.strip('"') for s in l.strip('[]').split(',') for l in open( 'myfile.txt', 'r' ).readlines() ]

I think that should work…I didn’t check it in an interpreter. The idea here is to give you an idea of how you can roll together Pythons very powerful list processing functions with its equally awesome string processing functions.

Remember, read documentation!

Good Luck!
