I want to find multiple spaces in a string using python. How to check if multiple spaces exist in a string?
mystring = 'this is a test'
I have tried the below code but it does not work.
if bool(re.search(' +', ' ', mystring))==True:
# ....
The result must return True.
You can use split() if you give no delimiter it will consider space as delimiter. after split check the length.If the length is greater than one it has spaces.
mystring = 'this is a test'
if len(mystring.split()) > 1:
#do something
len(mystring.split()) is > 1 even if mystring contains single spacesYou can use the string.count() method: If you want to check if multiple (more than one and no matter what their length) spaces exist the code is:
mystring.count(' ')>1
If you want to check if there is at least one consecutive space the code is:
mystring.count(' ')>=1
inYou can use re and compare the strings like this:
import re
mystring = 'this is a test'
new_str = re.sub(' +', ' ', mystring)
if mystring == new_str:
print('There are no multiple spaces')
else:
print('There are multiple spaces')
The syntax you use for re.search is wrong. It should be re.search(pattern, string, flags=0).
So, you can just do, searching for 2 or more spaces:
import re
def contains_multiple_spaces(s):
return bool(re.search(r' {2,}', s))
contains_multiple_spaces('no multiple spaces')
# False
contains_multiple_spaces('here are multiple spaces')
# True
