Hello guys I have the list of [0.5, 1.5, 2.5, 3.5]
def calc_mean(arglist):
return sum(arglist)/len(arglist)
print(calc_mean([0.5, 1.5, 2.5, 3.5]))
And then the same list but the elements are strings [‘0.5′,’1.5′,’2.5′,’3.5’] and I need to convert them to floats and then calculate the average but I’m getting the error (unsupported operand type(s) for +: ‘int’ and ‘str’) because the line return sum(arglist)/len(arglist) is working with integers and strlist is a string why strlist isn’t being converted to a float and it’s being treated as a str even though I converted it using [float(i) if ‘.’ in i else int(i) for i in strlist]
def str2float(strlist):
flist = [float(i) if '.' in i else int(i) for i in strlist]
return flist
strlist = ['0.5','1.5','2.5','3.5']
print(str2float(strlist))
print(calc_mean(strlist))
>Solution :
print(calc_mean(strlist))
As noted in comments, you have not converted strlist before passing it to calc_mean.
print(calc_mean(str2float(strlist)))
