while loop (Python)

Question

If I wanted to say something for a while loop such as: while time is greater than or equal to 0, would it simply be written as while time > or == 0? Or is there no way to do this?

The relation "is greater than or equal to" is treated as a single statement, not an alternation of two disjoint ones. The presence of the word "or" in the English reading doesn't imply that the operator or is involved in the translation to Python. In mathematics, this "greater than or equal" relationship is written with the symbol ≥, but usually in programming languages, and certainly in Python, it's written >=. — Mark Reed

Use while time >= 0 (equivalent to while time > 0 or time == 0)

>>> 0 >= 0
True
>>> 1 >= 0
True
>>> -1 >= 0
False

It would be:

while time >= 0:
    pass
    #here be dragons

Counting in Python example:

time = 0 
while time < 100: 
    time = time + 1 
    print time
