How Can I Import CSV Files into Pandas DataFrames?

Import CSV Files as Pandas DataFrames

Importing comma-separated values (CSV) files into a Pandas DataFrame is a common task in data analysis. To achieve this, Pandas provides a convenient function: pandas.read_csv.

How to Use pandas.read_csv

To read a CSV file into a DataFrame, simply call the read_csv function and provide the path to the file as an argument. Here's a simple example:

import pandas as pd
df = pd.read_csv("data.csv")
Copy after login

Once the DataFrame is created, you can access its contents using the usual methods:

print(df)
Copy after login

This will output:

        Date    price  factor_1  factor_2
0  2012-06-11  1600.20     1.255     1.548
1  2012-06-12  1610.02     1.258     1.554
2  2012-06-13  1618.07     1.249     1.552
3  2012-06-14  1624.40     1.253     1.556
4  2012-06-15  1626.15     1.258     1.552
5  2012-06-16  1626.15     1.263     1.558
6  2012-06-17  1626.15     1.264     1.572
Copy after login

Additional Options

pandas.read_csv also supports various optional arguments to customize the loading process. For example, you can specify the separator used in the CSV file using the sep argument:

df = pd.read_csv("data.csv", sep="|")
Copy after login

Additionally, you can skip specific rows in the CSV file using the skiprows argument:

df = pd.read_csv("data.csv", skiprows=1)
Copy after login
