NumPy strings.strip()
The numpy.strings.strip() function removes leading and trailing characters from each element in an array-like structure. By default, it removes whitespace, but a custom set of characters can be specified.
Syntax

Copy
numpy.strings.strip(a, chars=None)Parameters
| Parameter | Type | Description |

a | array-like, with StringDType, bytes_, or str_ dtype | The input array containing strings to be stripped. |

Copy
import numpy as np
# Define an array of strings with leading and trailing spaces
fruits = np.array([" apple ", " banana", "cherry "], dtype="str")
# Strip whitespace from both ends
stripped_fruits = np.strings.strip(fruits)
# Print the results
print("Original:", fruits)
print("Stripped:", stripped_fruits)Output:
Original: [' apple ' ' banana' 'cherry ']
Stripped: ['apple' 'banana' 'cherry']
