Pandas: Remove whitespaces, left sided whitespaces and right sided whitespaces of the string values of a given pandas series
Pandas: String and Regular Expression Exercise-2 with Solution
Write a Pandas program to remove whitespaces, left sided whitespaces and right sided whitespaces of the string values of a given pandas series.
Sample Solution:
Python Code :
import pandas as pd
color1 = pd.Index([' Green', 'Black ', ' Red ', 'White', ' Pink '])
print("Original series:")
print(color1)
print("\nRemove whitespace")
print(color1.str.strip())
print("\nRemove left sided whitespace")
print(color1.str.lstrip())
print("\nRemove Right sided whitespace")
print(color1.str.rstrip())
Sample Output:
Original series: Index([' Green', 'Black ', ' Red ', 'White', ' Pink '], dtype='object') Remove whitespace Index(['Green', 'Black', 'Red', 'White', 'Pink'], dtype='object') Remove left sided whitespace Index(['Green', 'Black ', 'Red ', 'White', 'Pink '], dtype='object') Remove Right sided whitespace Index([' Green', 'Black', ' Red', 'White', ' Pink'], dtype='object')

Previous: Write a Pandas program to convert all the string values to upper, lower cases in a given pandas series. Also find the length of the string values.
Next: Write a Pandas program to add leading zeros to the integer column in a pandas series and makes the length of the field to 8 digit.

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
