How to save a CSV file from the 21st row to the 45th row If I have a data frame of 100 rows
use head and tail
Here is an example of how you can save a csv file from row 21 to 45 of a data frame in Python: import pandas as pd
# Load your data frame
df = pd.read_csv('your_data_frame.csv')
# Select rows 21 to 45
df = df[20:45]
# Save the new data frame as a csv file
df.to_csv('subset_of_your_data_frame.csv', index=False) .
Note that the index starts from 0, so the 21st row is indexed as 20 and the 45th row is indexed as 44
