Increment integer in print statement

Question

I have this piece of code in python 3:

i=0
for item in splitDict(Team, 3):
    i+=1
    print("{1} #{0}".format(i,item))

What I'd like to do is:

i=0
for item in splitDict(Team, 3):
    print("{1} #{0}".format(i+=1,item))

Notice I've put the increment into the format statement. But when I run it I get the error:

print("{1} #{0}".format(i+=1,item))
                              ^
SyntaxError: invalid syntax

My question is how can I get it to increment in the print statement?

Why? Obscuring your code to save a line; you would have trouble finding a popular language where that is less idiomatic than python. — Nir Friedman

Just use enumerate and you don't have to increment manually. — roganjosh

Assignment in Python is not an expression but a statement in itself. You can't use it where you're trying to use it. — kindall

Clearly you are really wanting to use enumerate to solve your problem. But to answer the specific question of "how can I increment i within the print statement" ... then you can do the following very ugly thing (its not strictly within):

i=0
for item in splitDict(Team, 3):
    i += print("{1} #{0}".format(i + 1, item)) or 1

But you shouldn't. Use enumerate:

for i, item in enumerate(splitDict(Team, 3)):
    print("{1} #{0}".format(i, item))

Many thanks. I'm at the beginning of my journey with python. Lessons liked this help mer understand what I should and shouldn't do.

sorry I couldn't get your original code working, this is the best I could come up with

splitDict = ['a','b','c','d','e']
x=0
for i,item in enumerate(splitDict, start=x):
    print ('#'+str(i),item)
