Pandas: Extract email from a specified column of string type of a given DataFrame
Pandas: String and Regular Expression Exercise-24 with Solution
Write a Pandas program to extract email from a specified column of string type 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({
'name_email': ['Alberto Franco [email protected]','Gino Mcneill [email protected]','Ryan Parkes [email protected]', 'Eesha Hinton', 'Gino Mcneill [email protected]']
})
print("Original DataFrame:")
print(df)
def find_email(text):
email = re.findall(r'[\w\.-][email protected][\w\.-]+',str(text))
return ",".join(email)
df['email']=df['name_email'].apply(lambda x: find_email(x))
print("\Extracting email from dataframe columns:")
print(df)
Sample Output:
Original DataFrame: name_email 0 Alberto Franco [email protected] 1 Gino Mcneill [email protected] 2 Ryan Parkes [email protected] 3 Eesha Hinton 4 Gino Mcneill [email protected] \Extracting email from dataframe columns: name_email email 0 Alberto Franco [email protected] [email protected] 1 Gino Mcneill [email protected] [email protected] 2 Ryan Parkes [email protected] [email protected] 3 Eesha Hinton 4 Gino Mcneill [email protected] [email protected]

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")
