# 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 
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]
```
