How to Use all() in Python

result = all(data)
print(result) # Output: True
Example 2:
It can be used with a list comprehension to check conditions for all elements in a list.
numbers = [1, 2, 3, 4, 5]
result = all(x > 0 for x in numbers)
print(result) # Output: True
Example 3:
If any item in the iterable is false, the all() function will return False.
data = [True, False, True]
