any

logic

Returns True if at least one element of the iterable is true. Evaluates lazily.

Syntax

any(iterable)

any() gives you a yes-or-no answer and never the element that matched; when you need the element itself, reach for next() over a generator with a default value. Pass a generator expression rather than a list comprehension inside the parentheses — the comprehension builds every result first, so the early exit on the first true item is lost.

Examples

print(any([False,True,False]))  # → True
print(any([False,False]))  # → False
print(any([]))  # → False
print(any(x<0 for x in [1,-1,3]))  # → True
print(any(x==5 for x in range(10)))  # → True

# ленивое вычисление — остановится на первом True
print(any(x > 100 for x in range(10**6)))  # → True
