Use the strip() Function to Remove a Newline Character From the String in Python. The strip() function is used to remove both trailing and leading newlines from the string that it is being operated on. It also removes the whitespaces on both sides of the string.
Using strip() method to remove the newline character from a string. The strip() method will remove both trailing and leading newlines from the string. It also removes any whitespaces on both sides of a string.
Remove \n From the String in Python Using the str. strip() Method. In order to remove \n from the string using the str. strip() method, we need to pass \n and \t to the method, and it will return the copy of the original string after removing \n and \t from the string.
Use str.split([sep[, maxsplit]]) with no sep or sep=None:
From docs:
If
sepis not specified or isNone, 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
import re
mystr = "I want to Remove all white \t spaces, new lines \n and tabs \t"
print re.sub(r"\W", "", mystr)
Output : IwanttoRemoveallwhitespacesnewlinesandtabs
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
Good day!
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, '')
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 = 'https://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'<!DOCTYPE html>\r\n\r\n\r\n <html itemscope itemtype="http://schema.org/QAPage" class="html__responsive">\r\n\r\n <head>\r\n\r\n <title>string - Strip spaces/tabs/newlines - python - Stack Overflow</title>\r\n <link
This is what I changed it to:
import requests
import re
url = 'https://stackoverflow.com/questions/10711116/strip-spaces-tabs-newlines-python' # noqa
headers = {'user-agent': 'my-app/0.0.1'}
r = requests.get(url, headers=headers)
regex = r'\s+'
print("CNT: {}".format(re.sub(regex, " ", r.content.decode('utf-8'))))
Desired Result:
<!DOCTYPE html> <html itemscope itemtype="http://schema.org/QAPage" class="html__responsive"> <head> <title>string - Strip spaces/tabs/newlines - python - Stack Overflow</title>
The precise regex that @MattH had mentioned, was what worked for me in fitting it into my code. Thanks!
