How to check if the line contains special characters? (python)

To find out if character sets intersect:

>>> not set(".,:;!_*-+()/#¤%&)").isdisjoint("Booster!") True 

set.isdisjoint finds out if the sets are unbound.

You can use regular expressions:

 >>> import re >>> has_special = re.compile("|".join(map(re.escape, ".,:;!_*-+()/#¤%&)"))).search >>> bool(has_special("Booster!")) True 

Or a simple loop (quadratic algorithm):

 >>> text = "Booster!" >>> any(char in ".,:;!_*-+()/#¤%&)" for char in text) True 

More general case:

 import string print string.punctuation #выводит !"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ 

then through replace () you can delete what you don’t need

Getting these special characters:

 s = ".,:;!_*-+()/#¤%&" my_string="Booster!" set(s)&set(s1) # выведет общие символы, то есть ! len(set(s)&set(s1))>0 # выведет True s = ".,:;!_*-+()/#¤%&" my_string="Booster!" any(x for x in s if x in my_string) # выведет True, если есть общие спецсимволы. 

You can use the if x in y construction: Here, for example:

 def strng(word): s = ".,:;!_*-+()/#%&" for char in s: if char in word: print "The character " + char + " is in the word." else: pass strng("Boost!")
