How to compare string sizes in python

Python's string comparison is similar to Java, and also requires a comparison function, and the == symbol cannot be used. Use the cmp() method to compare two objects. If they are equal, 0 will be returned. If the former is greater than the latter, 1 will be returned. If they are less, -1 will be returned.

Example:

a = "abc"
b = "abc"
c = "aba"
d = "abd"
print cmp(a,b)
print cmp(a,c)
print cmp(a,d)

Return

0
1
-1

Note:

The cmp function has been removed from python3.

You can use == to compare strings, and the effect is the same as the cmp function. You can also use is.

>>> a='abc'
>>> b='abc'
>>> a is b
True
>>> id(a) == id(b)
True
>>>
