Python Exercises: Find the largest odd number in a list of integers
Python List: Exercise - 276 with Solution
Write a Python program to find the largest odd number in a given list of integers.
Sample Data:
([0, 9, 2, 4, 5, 6]) -> 9
([-4, 0, 6, 1, 0, 2]) -> 1
([1, 2, 3]) -> 3
([-4, 0, 5, 1, 0, 1]) -> 5
Sample Solution-1:
Python Code:
def test(nums):
odd_nums = [x for x in nums if x%2!=0]
return -1 if len(odd_nums) == 0 else max(odd_nums)
nums = [0, 9, 2, 4, 5, 6]
print("Original list:")
print(nums)
print("Find the largest odd number in the said list:", test(nums))
nums = [-4, 0, 6, 1, 0, 2]
print("\nOriginal list:")
print(nums)
print("Find the largest odd number in the said list:", test(nums))
nums = [1, 2, 3]
print("\nOriginal list:")
print(nums)
print("Find the largest odd number in the said list:", test(nums))
nums = [-4, 0, 5, 1, 0, 1]
print("\nOriginal list:")
print(nums)
print("Find the largest odd number in the said list:", test(nums))
Sample Output:
Original list: [0, 9, 2, 4, 5, 6] Find the largest odd number in the said list: 9 Original list: [-4, 0, 6, 1, 0, 2] Find the largest odd number in the said list: 1 Original list: [1, 2, 3] Find the largest odd number in the said list: 3 Original list: [-4, 0, 5, 1, 0, 1] Find the largest odd number in the said list: 5

Sample Solution-2:
Python Code:
def test(nums):
result = -1
for x in nums:
if x % 2 and x > result:
result = x
return result
nums = [0, 9, 2, 4, 5, 6]
print("Original list:")
print(nums)
print("Find the largest odd number in the said list:", test(nums))
nums = [-4, 0, 6, 1, 0, 2]
print("\nOriginal list:")
print(nums)
print("Find the largest odd number in the said list:", test(nums))
nums = [1, 2, 3]
print("\nOriginal list:")
print(nums)
print("Find the largest odd number in the said list:", test(nums))
nums = [-4, 0, 5, 1, 0, 1]
print("\nOriginal list:")
print(nums)
print("Find the largest odd number in the said list:", test(nums))
Sample Output:
Original list: [0, 9, 2, 4, 5, 6] Find the largest odd number in the said list: 9 Original list: [-4, 0, 6, 1, 0, 2] Find the largest odd number in the said list: 1 Original list: [1, 2, 3] Find the largest odd number in the said list: 3 Original list: [-4, 0, 5, 1, 0, 1] Find the largest odd number in the said list: 5

Python: Tips of the Day
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]
