    if statement - None value in python dictionary - Stack Overflow

    Define your dictionary with. d = {'a': None} rather than. d = {'a': 'None'} In the latter case, 'None' is just a string, not Python's None type. Also, test for None with the identity operator is: for key, value in d.iteritems(): if value is None: print "None found!"

    Your none values are actually strings in your dictionary.

    You can check for 'None' or use actual python None value.

    d = {'a':None,'b':'12345','c':None}

    for k,v in d.items():
    if d[k] is None:
    print "good"
    else:
    print "Bad"

    prints "good" 2 times

    Or if you Have to use your current dictionary just change your check to look for 'None'

    additionally dict is a python built in type so it is a good idea not to name variables dict
