Python: Remove words from a given list of strings containing a character or string
Python List: Exercise - 127 with Solution
Write a Python program to remove words from a given list of strings containing a character or string.
Sample Solution:
Python Code:
def remove_words(in_list, char_list):
new_list = []
for line in in_list:
new_words = ' '.join([word for word in line.split() if not any([phrase in word for phrase in char_list])])
new_list.append(new_words)
return new_list
str_list = ['Red color', 'Orange#', 'Green', 'Orange @', "White"]
print("Original list:")
print("list1:",str_list)
char_list = ['#', 'color', '@']
print("\nCharacter list:")
print(char_list)
print("\nNew list:")
print(remove_words(str_list, char_list))
Sample Output:
Original list: list1: ['Red color', 'Orange#', 'Green', 'Orange @', 'White'] Character list: ['#', 'color', '@'] New list: ['Red', '', 'Green', 'Orange', 'White']

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")
