I am trying to work out a simple function to capture typos, e.g: "Westminister15"
"Westminister15London"
"23Westminister15London"
after fixating: ["Westminister", "15"]
["Westminister", "15", "London"]
["23", "Westminister", "15", "London"]
First attempt: def fixate(query):
digit_pattern = re.compile(r'\D')
alpha_pattern = re.compile(r'\d')
digits = filter(None, digit_pattern.split(query))
alphas = filter(None, alpha_pattern.split(query))
print digits
print alphas
result: fixate("Westminister15London")
> ['15']
> ['Westminister', 'London']
However, I think this could be done more effectively, and I still get bad results when I try something like: fixate("Westminister15London England")
> ['15']
> ['Westminister', 'London England']
Obviously it should enlist London and England separately, but I feel my function will get overly patched and theres a simpler approach This question is somewhat equivalent to
this php question View Discussion Improve Article Save Article ReadDiscussView Discussion Improve Article Save Article Given string str, divide the string into three parts one containing a numeric part, one containing alphabetic, and one containing special
characters. Examples: Input : geeks01for02geeks03!!!
Output :geeksforgeeks
010203
!!!
Here str = "Geeks01for02Geeks03!!!", we scan every character and
append in res1, res2 and res3 string accordingly.
Input : **Docoding123456789everyday##
Output :Docodingeveryday
123456789
**##Steps : - Calculate the length of the string.
- Scan every character(ch) of a string one by one
- if (ch is a digit) then append it in res1 string.
- else if (ch is alphabet) append in string res2.
- else append in string res3.
- Print all the strings, we will have one string containing a numeric part, other non-numeric part, and the last one contains
special characters.

How do you separate letters in Python?
Use the list() class to split a word into a list of letters, e.g. my_list = list(my_str) . The list() class will convert the string into a list of letters. Copied!
How do you split text and numbers in Python?
split() method to split a string into text and number, e.g. my_list = re. split(r'(\d+)', my_str) . The re. split() method will split the string on the digits and will still include them in the list.
How do you split special characters in Python?
Use the re. split() method to split a string on all special characters. The re. split() method takes a pattern and a string and splits the string on each occurrence of the pattern.
