I want to print out the sum of str and float number by using the type function but somehow it's not working
var1,var2,var3=[str(2),float(3.0),str(5)]
print([var1,var2,var3])
if I simply apply plus function print(var1+var2+var3) it gives an error which I don't understand
TypeError: must be str, not float
You need to write:
print(sum(float(i) for i in [var1,var2,var3]))
But instead you can easily use it as below:
values = [str(2),float(3.0),str(5)]
in case the types are not matching you need to convert it to same type and then add it so you can do in one line by list comprehension as below:
float_values = [float(i) for i in values] # list of all values as float
print(sum(float_values))
+ operator
when you use strings with + operator it will concatenate strings
Ex.
x = '4' + '5' # result will be '45'
If you use it for integer it will give you addition of values Ex.
x = 4 + 5 # result will be 9
