Splitting a string where it switches between numeric and alphabetic characters

Question

I am parsing some data where the standard format is something like 10 pizzas. Sometimes, data is input correctly and we might end up with 5pizzas i

Answer added as possible way to solve How to split a string into a list by digits? which was dupe-linked to this question.

You can do the splitting yourself:

• use a temporary list to accumulate characters that are not digits
• if you find a digit, add the temporary list (''.join()-ed) to the result list (only if not empty) and do not forget to clear the temporary list
• repeat until all characters are processed and if the temp-lists still has content, add it

---

text = "Ka12Tu12La"

splitted = []   # our result
tmp = []        # our temporary character collector

for c in text:
    if not c.isdigit():
        tmp.append(c)    # not a digit, add it

    elif tmp:            # c is a digit, if tmp filled, add it  
        splitted.append(''.join(tmp))
        tmp = []

if tmp:
    splitted.append(''.join(tmp))

print(splitted)

Output:

['Ka', 'Tu', 'La']
