# Find the Largest Number in an Array | CSOTD #21 min read

• 1 Comment Today’s Code Snippet of the Day is a simple Python function to find the largest number in an array:

Code:

``````def find_largest_number(array):
"""Finds the largest number in an array.

Args:
array: A list of numbers.

Returns:
The largest number in the array.
"""

largest_number = array
for number in array:
if number > largest_number:
largest_number = number

return largest_number

# Example usage:

array = [1, 5, 3, 7, 2]
largest_number = find_largest_number(array)

print(largest_number)``````

Output:

``7``

In the above example, we have first defined a function in Python, in which there is a variable named `largest_number` is defined which triggers the first element in the array. Then it iterates over the array and compares each element present in the array, If any element is greater than the `largest_number` variable, `largest_number` variable is updated to that element. Finally, the function returns the `largest_number` variable and displays the greatest number present in the array.
