How to convert following list having numbers as string into integer and float

Question

t = ["3.4","7","","-1.3","-5",""]

How to convert this list into integer and float for further ananlysis?

I have done this so far but i got error.

t = ["3.4","7","","-1.3","-5",""]

def integer_float(string):
    try:
        return int(string)
    except ValueError:
        return float(string)

for i in t:
    integer_float(i)

I got the error

ValueError: could not convert string to float:

What do you expect to be the result of converting `""` to a number? — mkrieger1, Jun 15 '17 at 23:30

because you can't parse empty string as int nor float. try:

int(string or "0")
