How to enter a Googol in Python?

Question

I've heard that Python does not have any upper limit with integers. So I wanted to give a try:

a = 1e100
b = 1
c = a + b + a
c - 2 * a
> 0.0

Unfortunately I realized that writing 1e2 returns a float while 100 returns an int.

I've then tested with long('1' + '0' * 100) which works.

a = long('1' + '0' * 100)
b = 1
c = a + b + a
c - 2 * a
> 1L

Is this solution the only way to affect a Googol to a variable?

Answer 1

You can get a Googol like so:

10**100
