NumPy: numpy.char.lstrip() function

numpy.char.lstrip() function

The numpy.char.lstrip() function is used to remove leading characters (typically whitespace) from the elements of a string array or a single string.

This function is useful in 'Data cleaning', 'Text processing', 'Data preprocessing' etc.

Syntax:

numpy.char.lstrip(a, chars=None)

Parameters:

Return value:

Output array of str or unicode, depending on input type.

Example: Removing leading whitespaces from a string using NumPy

import numpy as np 
str1 = '   Python NumPy'
print("Original string: ",str1)
print("After leading whitepsace are removed:")
print(np.char.lstrip(str1))

Output:

Original string:     Python NumPy
After leading whitepsace are removed:
Python NumPy

In the above example, the numpy.char.lstrip() function is used to demonstrate how to remove leading whitespace characters from a string using NumPy. The 'numpy.char.lstrip()' function is called with the input string str1. This function removes all leading whitespace characters from the input string and returns the modified string.
