Splitting Text and Numbers in a String with Python

Without regular expression

Many times when working with strings, you might feel the need to separate text from numbers. As I was surfing through programming guides, I found that achieving this using regular expressions is fairly straightforward.

However, if you are like me, you might find regular expressions unreasonably difficult. Therefore, I came up with a simple algorithm that does the job.

Please feel free to look at the code and take a moment to see if the explanation below makes sense to you.

def split_text_from_digit(string):
    result = []
    text = ''
    digit = ''
    prev_char = None 
    for char in string:
        if char.isdigit():
            
            if prev_char == "digit" or prev_char==None:
                digit+=char
            else:
                if text != '':
                    result.append(text)
                text = ''
                digit = ''
                digit+=char
                
            prev_char = "digit"
            
        else:
            if prev_char == "text" or prev_char==None:
                text+=char
               
            else:
                if digit != '':
                    result.append(digit)
                digit = ''
                text = ''
                text+=char…
