# Python Exercises: Check if each number is prime in a list of numbers

## Python List: Exercise - 279 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

**Generates a list, containing the Fibonacci sequence, up until the nth term:**

Example:

def fibonacci(n): if n <= 0: return [0] sequence = [0, 1] while len(sequence) <= n: next_value = sequence[len(sequence) - 1] + sequence[len(sequence) - 2] sequence.append(next_value) return sequence print(fibonacci(7))

Output:

[0, 1, 1, 2, 3, 5, 8, 13]
