how to remove zeros after decimal from string remove all zero after dot

Question

I have data frame with a object column lets say col1, which has values likes: 1.00, 1, 0.50, 1.54

I want to have the output like the below: 1, 1, 0.5, 1.54 basically

Answer 1

I think something like this should work:

if val.is_integer() == True :
    val = int(val)
elif val.is_float() == True :
    val = Decimal(val).normalize()

Assuming that val is a float value inside the dataframe's column. You simply cast the value to be integer. For float value instead you cut extra zeros.
