Find Output of Python programs | Set 2 (Basics)

Here, we have some of the Python basic programs (calculation based), and we have to find their outputs. Each program has correct output along with their explanation.

Program 1:

a = 10
b = 3

res = a/b 
print "a/b: ", res 

res = float(a/b)
print "float (a/b) : ", res 

res = float (a) /float (b)
print "float (a/b) : ", res 

res = a/b 
print "a/b: ", res

Output

    a/b:  3
    float (a/b) :  3.0
    float (a/b) :  3.33333333333
    a/b:  3

Explanation:

• The values of a and b are integer type.
• Result of a/b will be an integer, thus the output of a/b will be 3.
• The statement float(a/b) will convert the result in float, a/b will be 3. Thus, float(a/b) = float(3) = 3.0. Output will be 3.0
• The statement float(a)/float(b)) will cast type the value of a and b and values will be 10.0 and 3.0. Thus the result of float(a)/float(b) will be 3.33333333333
• The statement a/b returns the output without remainder i.e. the integer part of the result will be printed. Hence, he output will be 3.

Program 2:

a = 36.24
b = 24 

res = a/b 
print "a/b : ", res 

res = (a//b)
print "(a//b) : ", res

Output

    a/b :  1.51
    (a//b) :  1.0

Explanation:

• Value of a is float, so there is no need to cast type a or b, the output will be in float.
• Statement a/b will return the divide result. Thus, the output will be 1.51.
• Statement a//b will return only integer part of the result. Thus the output will be 1.0.
