How to find a float in a string - Python?

Question

I want to find the first float that appears in a string using Python 3.

I looked at other similar questions but I couldn't understand them and when I tried to implement them they didn't work for my case.

An example string would be

I would like 1.5 cookies please

I'm pretty sure there's more elegant solution, but this one works for your specific case:

s = 'I would like 1.5 cookies please'

for i in s.split():
    try:
        #trying to convert i to float
        result = float(i)
        #break the loop if i is the first string that's successfully converted
        break
    except:
        continue

print(result) #1.5
