How do i remove a tab from a string in python?

I am trying to remove all spaces/tabs/newlines in python 2.7 on Linux.

I wrote this, that should do the job:

myString="I want to Remove all white \t spaces, new lines \n and tabs \t"
myString = myString.strip[' \n\t']
print myString

output:

I want to Remove all white   spaces, new lines 
 and tabs

It seems like a simple thing to do, yet I am missing here something. Should I be importing something?

Use str.split[[sep[, maxsplit]]] with no sep or sep=None:

From docs:

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace.

Demo:

>>> myString.split[]
['I', 'want', 'to', 'Remove', 'all', 'white', 'spaces,', 'new', 'lines', 'and', 'tabs']

Use str.join on the returned list to get this output:

>>> ' '.join[myString.split[]]
'I want to Remove all white spaces, new lines and tabs'

If you want to remove multiple whitespace items and replace them with single spaces, the easiest way is with a regexp like this:

>>> import re
>>> myString="I want to Remove all white \t spaces, new lines \n and tabs \t"
>>> re.sub['\s+',' ',myString]
'I want to Remove all white spaces, new lines and tabs '

You can then remove the trailing space with .strip[] if you want to.

Use the re library

import re
myString = "I want to Remove all white \t spaces, new lines \n and tabs \t"
myString = re.sub[r"[\n\t\s]*", "", myString]
print myString

Output:

IwanttoRemoveallwhitespaces,newlinesandtabs

This will only remove the tab, newlines, spaces and nothing else.

import re
myString = "I want to Remove all white \t spaces, new lines \n and tabs \t"
output   = re.sub[r"[\n\t\s]*", "", myString]

OUTPUT:

IwantoRemoveallwhiespaces,newlinesandtabs

The above solutions suggesting the use of regex aren't ideal because this is such a small task and regex requires more resource overhead than the simplicity of the task justifies.

Here's what I do:

myString = myString.replace[' ', ''].replace['\t', ''].replace['\n', '']

or if you had a bunch of things to remove such that a single line solution would be gratuitously long:

removal_list = [' ', '\t', '\n']
for s in removal_list:
  myString = myString.replace[s, '']

How about a one-liner using a list comprehension within join?

>>> foobar = "aaa bbb\t\t\tccc\nddd"
>>> print[foobar]
aaa bbb                 ccc
ddd

>>> print[''.join[[c for c in foobar if c not in [' ', '\t', '\n']]]]

Since there is not anything else that was more intricate, I wanted to share this as it helped me out.

This is what I originally used:

import requests
import re

url = '//stackoverflow.com/questions/10711116/strip-spaces-tabs-newlines-python' # noqa
headers = {'user-agent': 'my-app/0.0.1'}
r = requests.get[url, headers=headers]
print["{}".format[r.content]]

Undesired Result:

b'\r\n\r\n\r\n    \r\n\r\n    \r\n\r\n        string - Strip spaces/tabs/newlines - python - Stack Overflow\r\n
