Extract int digits and float number from a python string

Question

I have a string for example:

str1 = \"\'107.8X98x3.75\'\"
[107.8, 98, 3.75]
str2 = \'L=130.5mm;L=90mm\'
[130.5, 90]
str3 = \'圓278.5x15t 304\'
[278.5, 15, 304         


        

Answer 1

How about regular expressions?

Example

>>> import re
>>> str1="107.8X98x3.75"
>>> re.findall(r'\d+(?:\.\d+)?', str1)
['107.8', '98', '3.75']
