Concatenating user input?

I want to concatenate user input with a ':' colon in-between.

My script is taking options through user input and I want to store it like:

Red:yellow:blue

I have created a loop to read user input, but not sure how to store it.

while True:
    color = input("please enter Color of your choice(To exit press No): ")
    if color == 'No':
        break
    color += color
print ("colors   ", color)

Using a list is neat:

colors = []
while True:
    color = input("please enter Color of your choice(To exit press No): ")
    if color in ('No'):
        break
    colors.append(color)
print("colors   ", ':'.join(colors))

One simple approach to keep as close to your code as possible is to start off with an empty list called colors before entering your loop, and appending to that all the valid colors as you take inputs. Then, when you are done, you simply use the join method to take that list and make a string with the ':' separators.

colors = []
while True:
     color = input("please enter Color of your choice(To exit press No): ")
     if color == 'No':
       break
     else:
         colors.append(color)

colors = ':'.join(colors)
print ("colors   ", colors)

Demo:

please enter Color of your choice(To exit press No): red
please enter Color of your choice(To exit press No): blue
please enter Color of your choice(To exit press No): green
please enter Color of your choice(To exit press No): orange
please enter Color of your choice(To exit press No): No
colors    red:blue:green:orange

you're looking for str.join(), to be used like so: ":".join(colors). Read more at https://docs.python.org/2/library/stdtypes.html#str.join

You can concatenate a ':' after every input color

while True:
     color = input("please enter Color of your choice(To exit press No): ")
     if color == 'No':
       break
     color += color
     color += ':'
print ("colors   ", color)
