Pandas: String and Regular Expression Exercise-35 with Solution

Write a Pandas program to check whether two given words present in a specified column of a given DataFrame.

Sample Solution:

Python Code :

import pandas as pd
import re as re
pd.set_option('display.max_columns', 10)
df = pd.DataFrame({
    'company_code': ['c0001','c0002','c0003', 'c0003', 'c0004'],
    'address': ['9910 Surrey Ave.','92 N. Bishop Ave.','9910 Golden Star Ave.', '102 Dunbar St.', '17 West Livingston Court']
    })
print("Original DataFrame:")
print(df)
def test_and_cond(text):
    result = re.findall(r'(?=.*Ave.)(?=.*9910).*', text) 
    return " ".join(result)
df['check_two_words']=df['address'].apply(lambda x : test_and_cond(x))
print("\nPresent two words!")
print(df)

Sample Output:

Original DataFrame:
  company_code                   address
0        c0001          9910 Surrey Ave.
1        c0002         92 N. Bishop Ave.
2        c0003     9910 Golden Star Ave.
3        c0003            102 Dunbar St.
4        c0004  17 West Livingston Court

Present two words!
  company_code                   address        check_two_words
0        c0001          9910 Surrey Ave.       9910 Surrey Ave.
1        c0002         92 N. Bishop Ave.                       
2        c0003     9910 Golden Star Ave.  9910 Golden Star Ave.
3        c0003            102 Dunbar St.                       
4        c0004  17 West Livingston Court

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")
