Adjusting 1 space between two strings using python

Question

I have two strings:

>>> a = "abcd"
>>> b = "xyz"
>>> c = a + b
>>> c
abcdxyz

How can I get abcd xyz as a result instead when adding a and b ?

Answer 1

Simply just add a space between the two strings:

a = "abcd" 
b = "xyz" 
c = a + " " + b  # note the extra space concatenated with the other two
print c

this will give you

abcd xyz

You can use a function such as .join() , but for something so short, that would seem almost counter-intuitive (and IMO "overkill"). Ie, first create a list with the two strings, then call a function with that list and use the return of that function in a print statement ... when you can just concatenate the needed space with the 2 strings. Seems semantically more clear too.

Based on: "Simple is better than complex." ( The Zen of Python "import this" )

Answer 2

You can use join to concatenate your strings together with your selected delimiter.

a = "abcd"
b = "xyz"
c = " ".join([a, b])

Answer 3

Python supports the string formatting operations and a template system (the latter is technically a simple but powerful class) as part of the string module. While the plus operator does its work, the lack of string formatting can influence a lot the readability of the code. A basic example for string formatting:

c = '%s %s' % (a, b)

Answer 4

Since Python 3.6, you can use f-strings to join two strings with ease. The code is more succinct and the variables are referenced directly within the context of the string.

a = 'hello'
b = 'world'
c = f'{a} {b}'

print(c)

The above code would output the following:

hello world

The .join() function is still the way to go when you have many strings or where the number of strings may vary.

Answer 5

If you only need to print a space between the two, you can use this:

a = "hi"
b = "how r u"

print a,b
