Consider below statements in Python 2.7
First output is fine, but the second one may be surprising if we are coming Java/C++ world. In Python 2.7, the “/” operator works as a floor division for integer arguments. However, the operator / returns a float value if one of the arguments is a float (this is similar to C++)
The real floor division operator is “//”. It returns floor value for both integer and floating point arguments.
2 -3 2.0 -3.0
How about Python 3?
Here is another surprise, In Python 3, ‘/’ operator does floating point division for both int and float arguments.
# A Python 3 program to demonstrate use of # "/" for both integers and floating points print (5/2) print (-5/2) print (5.0/2) print (-5.0/2)
2.5 -2.5 2.5 -2.5
Behavior of “//” is same Python 2.7 and Python 3. See this for example.
