Question

I have some String like:

...etc

Does have any function can do:

>>> a = '% 0.9 Saline solution'
>>> some_clever(a)
>>> 6

>>> a[some_clever(a):]
>>>'Saline solution'

Thank you

Answer 1

To calculate the index, you can use next with a generator expression and str.isalpha / enumerate . Then use string slicing as normal. Here's a demo:

a = '% 0.9 Saline solution'
b = '2% Taurolidine Lock'
c = '2 DAA'

def get_string(x):
    idx = next(i for i, j in enumerate(x) if j.isalpha())
    return x[idx:]

for val in [a, b, c]:
    print(val, ':', get_string(val))

% 0.9 Saline solution : Saline solution
2% Taurolidine Lock : Taurolidine Lock
2 DAA : DAA
