Printing Lists in Python Without Spaces

Printing Values from a list without spaces in python 2.7

From your comments on @jftuga answer, I guess that the input you provided is not the one you're testing with. You have mixed contents in your list.

My answer will fix it for you:

lst = ['A','B',1,2]
print("".join([str(x) for x in lst]))

or

print("".join(map(str,lst)))

I'm not just joining the items since not all of them are strings, but I'm converting them to strings first, all in a nice generator comprehension which causes no memory overhead.

Works for lists with only strings in them too of course (there's no overhead to convert to str if already a str, even if I believed otherwise on my first version of that answer: Should I avoid converting to a string if a value is already a string?)

Print list without spaces

You need to use something like:

print('[{0}]'.format(','.join(map(str, l))))

python 2.7.5+ print list without spaces after the commas

The data in hand is a list of numbers. So, first we convert them to strings and then we join the join the strings with str.join function and then print them in the format [{}] using str.format, here {} represents the actual joined string.

data = [1,2, 3, 4]
print(data)                                       # [1, 2, 3, 4]
print("[{}]".format(",".join(map(repr, data))))   # [1,2,3,4]

data = ['aaa','bbb', 'ccc', 'ddd']
print(data)                                       # ['aaa', 'bbb', 'ccc', 'ddd']
print("[{}]".format(",".join(map(repr, data))))   # ['aaa','bbb','ccc','ddd']

If you are using strings

data = ['aaa','bbb', 'ccc', 'ddd']
print("[{}]".format(",".join(map(repr, data))))

Or even simpler, get the string representation of the list with repr function and then replace all the space characters with empty strings.

print(repr(data).replace(" ", ""))                 # [1,2,3,4]

Note: The replace method will not work if you are dealing with strings and if the strings have space characters in them.

How to print a list using splat-operator (*) without spaces

You get that result because print automatically puts spaces between the passed arguments. You need to modify the sep parameter to prevent the separation spaces from being inserted:

print(*word, sep="")  # No implicit separation space

How to print without spaces in python 3?

You can use the sep argument to print:

>>> income = 50000
>>> print("Your income tax is $", income, ".", sep='')
Your income tax is $50000.

Or use the str.format:

>>> print("Your income tax is ${}.".format(income))
Your income tax is $50000.

Print without space in python 3

You can use the sep parameter to get rid of the spaces:

>>> print("a","b","c")
a b c
>>> print("a","b","c",sep="")
abc

I don't know what you mean by "Java style"; in Python you can't add strings to (say) integers that way, although if a and b are strings it'll work. You have several other options, of course:

>>> print("a = ", a, ", b = ", b, sep="") 
a = 2, b = 3
>>> print("a = " + str(a) + ", b = " + str(b))
a = 2, b = 3
>>> print("a = {}, b = {}".format(a,b))
a = 2, b = 3
>>> print(f"a = {a}, b = {b}")
a = 2, b = 3

The last one requires Python 3.6 or later. For earlier versions, you can simulate the same effect (although I don't recommend this in general, it comes in handy sometimes and there's no point pretending otherwise):

>>> print("a = {a}, b = {b}".format(**locals()))
a = 2, b = 3
>>> print("b = {b}, a = {a}".format(**locals()))
b = 3, a = 2
