Python: Division - Hacker Rank Solution
Problem
Tutorial :
In Python, there are two kinds of division: integer division and float division.
Python 2 syntax
from __future__ import division # floating point division print 4 / 3 # integer division print 4 // 3
Python 3 syntax
print(4 / 3) print(4 // 3)
Gives the output
1.3333333333333333 1
Note: The __ in __future__ is a double underscore.
During the time of Python 2, when you divided one integer by another integer, no matter what, the result would always be an integer.
For example:
>>> 4/3 1
For example:
>>> 4/3.0 1.3333333333333333
Since Python doesn't declare data types in advance, you never know when you want to use integers and when you want to use a float. Since floats lose precision, it's not advised to use them in integral calculations.
To solve this problem, future Python modules included a new type of division called integer division given by the operator //.
Now, / performs float division, and // performs integer division.
In Python 2, we will import a feature from the module __future__ called division.
Read two integers and print two lines. The first line should contain integer division, a//b . The second line should contain float division, a/b.
You don't need to perform any rounding or formatting operations.
Input Format :
The first line contains the first integer, a. The second line contains the
second integer, b.
Output Format :
Print the two lines as described above.
Sample Input :
4 3
Sample Output :
1 1.33333333333
Solution :
1 2 3 4 5 6 7 8 9 10 | # Python: Division - Hacker Rank Solution from __future__ import division if __name__ == '__main__': a = int(raw_input()) b = int(raw_input()) # Python: Division - Hacker Rank Solution START print(a//b); print(a/b); # Python: Division - Hacker Rank Solution END |
