How to print very large natural numbers in Python in non exponential form?

The number can be very large

n = input()
print(n) #gives output in scientific notation

How to get the entire number?

PS: New to python

EDIT:

s = (input())      #100000000000000000000000000000000000000
if int(s[-1])%2 == 0:
    print (2)
    print (2)
    print (int(s)/2)         #5e+37

You can format a large number into a scientific notation using the {:2E} formatting code. Example:

>>> "{:.2E}".format(100000000000000000000000000000000000000)
'1.00E+38'

Another variation to do this:

>>> n = 100000000000000000000000000000000000000
>>> '%2E' % n
'1.000000E+38'

See this question for discussion about the stripping out the extra zeros from the output.

In Python 3, if you want integer division, use the // operator:

print(int(s) // 2)

The result of the division will be an integer and will not get printed out in the scientific notation.
