Removing Extra spaces in Python using a variable in 'for' Loop

Question

In a code:

a = 6
for i in range(a):
    print("case #",i)

While printing the output, as shown below:

case # 0
case # 1
case # 2
case # 3
case # 4
case # 5

There is an extra space between '#' and the variable 'i'. How to remove this space? In fact, if we normally write:

a = 'sam'
print("hello",a)

then also, the output is:

hello sam

there is an extra space between "hello" and "sam". How to remove this?

Try this:

print("hello",a , sep='')

sep is the separator of print function when you call in with more that one argument.

that's a great answer, actually, this remove spaces without converting them into the string – VIKAS RATHEE Oct 02 '18 at 10:48

You can just make one string from the two arguments, using +. Note: you have to convert i to string first.

a = 6
for i in range(a):
    print("case #"+str(i))

what is +str(i) here? – VIKAS RATHEE Oct 02 '18 at 10:41
`+` 'merges' the two strings into one string, but your `i` is an integer in the beginning, so I use `str()` function to convert it to a string first – Piotrek Oct 02 '18 at 10:42
@VIKASRATHEE, vikas to thank anyone on SO or encourage people who are trying to help you on SO you could give their answers up votes and try to select 1 of the answer as correct too(after sometime when you see few answers are there for you question). – RavinderSingh13 Oct 02 '18 at 10:49

Could you please try following too once.

a=6
for i in range(a):
   print 'case #%d' % (i)

Output will be as follows.

case #0
case #1
case #2
case #3
case #4
case #5
