Question

Question: How to extract "660" from list2

list2 = ['BIA-660', 'Web', 'Analytics']
c=list2[0]
x=c.split("-")
print(x[1])

I am getting the answer but Wanted to know if there is another more efficient way of achieving the solution.

Answer 1

You could use Regex to get any digits from a string

import re

list2 = ['BIA-660', 'Web', 'Analytics']

for strg in list2:
    found = re.findall('\d+', strg)
    if found != []:
        for num in found:
            print(num)

Output:

660

Answer 2

This will return a list of numbers contained in the string:

list2 = ['BIA-660', 'Web', 'Analytics']
s = '-'.join(list2)

# extract numbers from string
result = [int(txt) for txt in s.split('-') if txt.isdigit()]
print(result)

[660]
