>>The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts......Fact 2
If you have ever coded in C++ or Java then you'll be familiar with braces {} but for python, there's no chance
from __future__ import braces
>>SyntaxError: not a chance Fact 3
Fact 4
We can’t define Infinities right? But wait! Not for Python
# Positive Infinity
p_infinity = float('Inf')
if 99999999999999 > p_infinity:
print("The number is greater than Infinity!")
else:
print("Infinity is greatest")
>>Infinity is greatest
