Str(num1 + num 2)?

Question

If we don't use str command and add two numbers as float, can we show that with print("result is: ", num1+num2)?

Answer 1

Hope i understand what you mean:

num1 = 4.5
num2 = 7.2
print('result is: ', num1 + num2)
#output is: result is: 11.7

if you get the values for num1 and num2 from input() function numbers has to be converted to int or float. The reason is that input() always returns a string like ‘4.5’ and ‘7.2’. Addition can not be done with strings, the strings will be concatenated:

num1 = input(‘num1’)
num2 = input(‘num2’)
#num1 shows ‘4.5’
#num2 shows ‘7.2’
print('result is: ', num1 + ‘ ‘+ num2)
#output is: result is: “4.2 7.2”

to get int or float change input() to:

num1 = float(input(‘num1’))

Answer 2

Yes , str() constructs a string from a wide variety of data types, including strings, integer literals and float literals
