How to Print Variables Without Spaces Between Values [Duplicate]

Question

I would like to know how to remove additional spaces when I print something.

Like when I do:

print 'Value is "', value, '"'

The output will be:

Value is " 42 "

But I want:

Value is "42"

Is there any way to do this?

Accepted Answer

Don't use print ..., (with a trailing comma) if you don't want spaces. Use string concatenation or formatting.

Concatenation:

print 'Value is "' + str(value) + '"'

Formatting:

print 'Value is "{}"'.format(value)

The latter is far more flexible, see the str.format() method documentation and the Formatting String Syntax section.

You'll also come across the older % formatting style:

print 'Value is "%d"' % value
print 'Value is "%d", but math.pi is %.2f' % (value, math.pi)

but this isn't as flexible as the newer str.format() method.

In Python 3.6 and newer, you'd use a formatted string (f-string):

print(f"Value is {value}")

Answer 2

Just an easy answer for the future which I found easy to use as a starter: Similar to using end='' to avoid a new line, you can use sep='' to avoid the white spaces...for this question here, it would look like this: print('Value is "', value, '"', sep = '')

May it help someone in the future.

Answer 3

It's the comma which is providing that extra white space.

One way is to use the string % method:

print 'Value is "%d"' % (value)

which is like printf in C, allowing you to incorporate and format the items after % by using format specifiers in the string itself. Another example, showing the use of multiple values:

print '%s is %3d.%d' % ('pi', 3, 14159)

For what it's worth, Python 3 greatly improves the situation by allowing you to specify the separator and terminator for a single print call:

>>> print(1,2,3,4,5)
1 2 3 4 5

>>> print(1,2,3,4,5,end='<<\n')
1 2 3 4 5<<

>>> print(1,2,3,4,5,sep=':',end='<<\n')
1:2:3:4:5<<

Answer 4

print(*objects, sep=' ', end='\n', file=sys.stdout)

Note: This function is not normally available as a built-in since the name print is recognized as the print statement. To disable the statement and use the print() function, use this future statement at the top of your module:

from future import print_function

Answer 5

To build off what Martjin was saying. I'd use string interpolation/formatting.

In Python 2.x which seems to be what you're using due to the lack of parenthesis around the print function you do:

print 'Value is "%d"' % value

In Python 3.x you'd use the format method instead, so you're code would look like this.

message = 'Value is "{}"'
print(message.format(value))

Answer 6

>>> value=42

>>> print "Value is %s"%('"'+str(value)+'"') 

Value is "42"
