examples/pitfalls/random.py

import random

print(random.random())

$ python examples/pitfalls/random.py

• Write an example to use random number and call your example number.py
• Same with any other module name.
• Lack of multi-level namespaces
• Solution: user longer names. Maybe with project specific names.
