Python Converting string into a list ignoring the special characters

I am having a string as :- 

'Current Weather\n\t\n\n\t\t12:36 AM\n\t\n\n\n\n\t\t\t22°\n\t\t\n\n\t\t\t\tC\n\t\t\t\n\n\n\t\tRealFeel®\n\t\t20°\n\t\n\n\t\tMostly clear'

I want to convert it into a list as :-

['Current Weather','12:36 AM','22°','C','RealFeel®','20°','Mostly clear']

Is there any python module or function with which I can do so?

You can use re.split:

import re

s = 'Current Weather\n\t\n.....t\tMostly clear'
re.split(r'[\n\t]+', s)

Output:

['Current Weather', '12:36 AM', '22°', 'C', 'RealFeel®', '20°', 'Mostly clear']

You could use Python regex. Here is an example:

import re
def sentance_to_list(sentence):
ls=re.split(r'["\t|\n"]\s*', sentence)   # split \t or \n
return ls

strr='Current Weather\n\t\n\n\t\t12:36 AM\n\t\n\n\n\n\t\t\t22°\n\t\t\n\n\t\t\t\tC\n\t\t\t\n\n\n\t\tRealFeel®\n\t\t20°\n\t\n\n\t\tMostly clear'
newstrr=sentance_to_list(strr)
print(newstrr)

output:

['Current Weather', '12:36 AM', '22°', 'C', 'RealFeel®', '20°', 'Mostly clear']

You could read more on re https://docs.python.org/3/library/re.html

Why is everybody using re? This library is very slow.You can just use str.split,if you use it with arguments,you will have to do the str.isspace by hand,but it's still pretty fast,this is the code:

>>> [i.strip() for i in s.split('\n\t') if not i.isspace()]
['Current Weather', '12:36 AM', '22°', 'C', 'RealFeel®', '20°', 'Mostly clear']

Benchmarks:

>>> timeit.timeit(r"re.split(r'[\n\t]+', s)",r"""
import re
s = 'Current Weather\n\t\n\n\t\t12:36 AM\n\t\n\n\n\n\t\t\t22°\n\t\t\n\n\t\t\t\tC\n\t\t\t\n\n\n\t\tRealFeel®\n\t\t20°\n\t\n\n\t\tMostly clear'
""")

timeit.timeit(r"[i.strip() for i in s.split('\n\t') if not i.isspace()]",r"""import re

s = 'Current Weather\n\t\n\n\t\t12:36 AM\n\t\n\n\n\n\t\t\t22°\n\t\t\n\n\t\t\t\tC\n\t\t\t\n\n\n\t\tRealFeel®\n\t\t20°\n\t\n\n\t\tMostly clear'
""")

Without regex:

[x.strip() for x in st.splitlines() if x.strip()!= '']

output:

['Current Weather', '12:36 AM', '22°', 'C', 'RealFeel®', '20°', 'Mostly clear']
