Python program to find Tuples with positive elements in a List of tuples

When it is required to find tuples with positive elements in a list of tuples, list comprehension and ‘all’ operator is used.

Example

Below is a demonstration of the same −

my_tuple = [(14, 15, 19), (-32, 23, 32), (-31, 15, 63), (46, 68)]

print("The list is :")
print(my_tuple)

my_result = [sub for sub in my_tuple if all(element >= 0 for element in sub)]

print("The result is :")
print(my_result)

Output

The list is :
[(14, 15, 19), (-32, 23, 32), (-31, 15, 63), (46, 68)]
The result is :
[(14, 15, 19), (46, 68)]

Explanation

• A list of tuple of integers is defined and is displayed on the console.

• A list comprehension is used to iterate over the elements and check if element is greater than 0.

• This is done using ‘all’ operator and is converted to a list.

• This is assigned to a variable.

• This is the output that is displayed on the console.
