np.char.endswith() method - Python

The np.char.endswith() method is used to check whether each string in a NumPy array ends with a specified substring.

For Example: This example checks whether each string in a 1D array ends with the letter "s".

Array: ['cats' 'dogs' 'fish']
Result: [ True True False]

Explanation:

• "cats" and "dogs" end with "s" -> True
• "fish" does not end with "s" -> False

Syntax

np.char.endswith(a, suffix)

Parameters:

• a: array_like of str -> Input array of strings.
• suffix: str -> Substring to check at the end of each string.

Return Value: ndarray of bool -> Boolean array indicating whether each string ends with the given substring.

Examples

Example 1: This example checks if strings in a 1D array end with "ks".

[ True False True]

Example 2: This example checks if strings in the array end with the digit "1".

[ True False False True]

Example 3: This example shows that the method is case-sensitive.
