How to remove space between variable and string in python

My code looks like this:

name = Joe
print "Hello", name, "!"

My output looks like:

Hello Joe !

How do I remove the space between Joe and !?

There are several ways of constructing strings in python. My favorite used to be the format function:

print "Hello {}!".format[name]

You can also concatenate strings using the + operator.

print "Hello " + name + "!"

More information about the format function [and strings in general] can be found here: //docs.python.org/2/library/string.html#string.Formatter.format

6 Years Later...

You can now use something called f-Strings if you're using python 3.6 or newer. Just prefix the string with the letter f then insert variable names inside some brackets.

print[f"Hello {name}"]

a comma after print will add a blank space.

What you need to do is concatenate the string you want to print; this can be done like this:

name = 'Joe'
print 'Hello ' +  name + '!'

Joe must be put between quotes to define it as a string.

>>> print [name]
Joe
>>> print['Hello ', name, '!']
Hello  Joe !
>>> print['Hello ', name, '!', sep='']
Hello Joe!

You can also use printf style formatting:

>>> name = 'Joe'
>>> print 'Hello %s !' % name
Hello Joe !

One other solution would be to use the following:

Print 'Hello {} !'.format[name.trim[]]

This removes all the leading and trailing spaces and special character.

Remove space between variable and string in Python #

Use a formatted string literal to remove the space between a variable and a string, e.g. result = f'{variable} world'. The variable can be interpolated right next to the string when using a formatted string literal.

Copied!
variable = 'hello'

# ✅ using formatted string literal
result = f'{variable} world'
print[result]  # 👉️ 'hello world'

# -----------------------------------------

# ✅ using the addition [+] operator

result = variable + ' world'
print[result]  # 👉️ hello world

# -----------------------------------------

# ✅ using str.join[] and str.split[]

variable = 'hello    '

result = ' '.join[f'{variable} world'.split[]]
print[result]  # 👉️ 'hello world'

# -----------------------------------------

# ✅ remove unnecessary whitespace when printing

variable = 'hello '

# 👇️ hello world!
print[variable, 'world', '!', sep='']

The first example uses a formatted string literal to remove the space between a variable and a string.

Copied!

  

variable = 'hello'

# ✅ using formatted string literal
result = f'{variable} world'
print[result]  # 👉️ 'hello world'

result = f'{variable}world'
print[result]  # 👉️ 'helloworld'

Formatted string literals [f-strings] let us include expressions inside of a string by prefixing the string with f.

Copied!
variable = 'hello'

variable_2 = 'world'

result = f'{variable} {variable_2}!'
print[result]  # 👉️ 'hello world!'

Make sure to wrap expressions in curly braces - {expression}.

Alternatively, you can use the addition [+] operator to concatenate the variable and the string without extra whitespace.

Copied!
variable = 'hello'

result = variable + ' world'
print[result]  # 👉️ 'hello world'

If you use the addition operator, you have to make sure that the values on the left and right-hand sides are of type string.

You can use the str[] class if you need to convert a value to a string, e.g. str[my_number].

If you have a string that contains multiple spaces next to one another, you can use the str.split[] and str.join[] methods to remove the extra whitespace.

Copied!
variable = 'hello    '

result = ' '.join[f'{variable} world'.split[]]
print[result]  # 👉️ 'hello world'

result = ''.join[f'{variable}world'.split[]]
print[result]  # 👉️ 'helloworld'

The str.split[] method splits the string into a list of substrings using a delimiter.

If no delimiter is passed to the method, the method splits the string on one or more occurrences of whitespace characters.

Copied!
variable = 'hello    '

# 👇️ ['hello', 'world']
print[f'{variable} world'.split[]]

The last step is to use the str.join[] method to join the list of strings.

The str.join method takes an iterable as an argument and returns a string which is the concatenation of the strings in the iterable.

The string the method is called on is used as the separator between the elements.

Copied!
variable = 'hello    '

result = ' '.join[f'{variable} world'.split[]]
print[result]  # 👉️ 'hello world'

result = ''.join[f'{variable}world'.split[]]
print[result]  # 👉️ 'helloworld'

If you need to remove extra spaces when using the print[] function, set the sep keyword argument to an empty string.

Copied!
variable = 'hello '

# 👇️ hello world!
print[variable, 'world', '!', sep='']

The sep keyword argument is the separator between the values.

By default, the sep argument is set to a space.

By setting the argument to an empty string, no extra whitespace is added between the values.
