Write a program in Python to store the city and state names that start with ‘k’ in a given DataFrame into a new CSV file
Input −
Assume, we have DataFrame with City and State columns and find the city, state name startswith ‘k’ and store into another CSV file as shown below −
City,State Kochi,Kerala
Solution
To solve this, we will follow the steps given below.
Define a DataFrame
Check the city starts with ‘k’ as defined below,
df[df['City'].str.startswith('K') & df['State'].str.startswith('K')]
Finally, store the data in the ‘CSV’ file as below,
df1.to_csv(‘test.csv’)
Example
Let us see the following implementation to get a better understanding.
import pandas as pd
import random as r
data = { 'City': ['Chennai','Kochi','Kolkata'],'State':
['Tamilnad','Kerala','WestBengal']}
df = pd.DataFrame(data)
print("DataFrame is\n", df)
df1 = df[df['City'].str.startswith('K') & df['State'].str.startswith('K')]
df1.to_csv('test.csv')Output
