Python Exercises: Check if each number is prime in a list of numbers
Python List: Exercise - 17 with Solution
Write a Python program to check if each number is prime in a given list of numbers. Return True if all numbers are prime otherwise False.
Sample Data:
([0, 3, 4, 7, 9]) -> False
([3, 5, 7, 13]) -> True
([1, 5, 3]) -> False
Sample Solution-1:
Python Code:
def test(nums):
return all(is_prime(i) for i in nums)
def is_prime(n):
if (n==1):
return False
elif (n==2):
return True;
else:
for x in range(2,n):
if(n % x==0):
return False
return True
nums = [0, 3, 4, 7, 9]
print("Original list of numbers:")
print(nums)
print("Check if each number is prime in the said list of numbers:")
print(test(nums))
nums = [3, 5, 7, 13]
print("\nOriginal list of numbers:")
print(nums)
print("Check if each number is prime in the said list of numbers:")
print(test(nums))
nums = [1, 5, 3]
print("\nOriginal list of numbers:")
print(nums)
print("Check if each number is prime in the said list of numbers:")
print(test(nums))
Sample Output:
Original list of numbers: [0, 3, 4, 7, 9] Check if each number is prime in the said list of numbers: False Original list of numbers: [3, 5, 7, 13] Check if each number is prime in the said list of numbers: True Original list of numbers: [1, 5, 3] Check if each number is prime in the said list of numbers: False

Sample Solution-2:
Python Code:
def test(nums):
result = [is_prime(i) for i in nums]
return all(result)
def is_prime(n):
if (n==1):
return False
elif (n==2):
return True;
else:
for x in range(2,n):
if(n % x==0):
return False
return True
nums = [0, 3, 4, 7, 9]
print("Original list of numbers:")
print(nums)
print("Check if each number is prime in the said list of numbers:")
print(test(nums))
nums = [3, 5, 7, 13]
print("\nOriginal list of numbers:")
print(nums)
print("Check if each number is prime in the said list of numbers:")
print(test(nums))
nums = [1, 5, 3]
print("\nOriginal list of numbers:")
print(nums)
print("Check if each number is prime in the said list of numbers:")
print(test(nums))
Sample Output:
Original list of numbers: [0, 3, 4, 7, 9] Check if each number is prime in the said list of numbers: False Original list of numbers: [3, 5, 7, 13] Check if each number is prime in the said list of numbers: True Original list of numbers: [1, 5, 3] Check if each number is prime in the said list of numbers: False

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
