Hi,
I'm trying to compare two strings because I want to find the difference.
i.e.
string1 = "foobar"
string2 = "foobzr"
is there a simple way to do this with a for loop? This is the method I
tried, but it gives me an error:
In [14]: for x, y in bar[0], bar[1]:
....: print x, y
With the zip() function you can merge two sequences into one:
for x, y in zip(string1, string2):
print x, y
will print something like
f f
o o
o o
b b
a z
r r
for x in xrange(0, len(bar[0])):
print bar[0][x], bar[1][x] #yes I realize there's no comparison here,
I know how to do that - this is just a placeholder
Not entirely valid in this case, but the pythonic way to have a value as well
as its index is by using the enumerate() function:
for idx, val in ['A', 'B', 'C']:
print idx, val
will print something like
0 A
1 B
2 C
Good luck,
Albert
