Create Pandas DataFrame from a string

Creating a Pandas DataFrame from a String 🐼

Are you looking to create a Pandas DataFrame from a string? Maybe you're trying to test some functionality or work with test data that's stored in a string rather than a file. Whatever the case may be, we've got you covered! In this guide, we'll explore the common issues and provide easy solutions on how to create a Pandas DataFrame from a string.

The Problem 🤔

Let's start by understanding the problem at hand. You have some test data stored as a string, like this:

TESTDATA="""col1;col2;col3
1;4.4;99
2;4.5;200
3;4.7;65
4;3.2;140
"""

You want to load this data into a Pandas DataFrame to work with it more efficiently. However, you may not be sure about the simplest way to achieve this.

The Solution 💡

Fortunately, Pandas provides a simple solution to create a DataFrame from a string using the read_csv() function. Even though our data is not in the CSV format, we can still leverage this function by customizing the separator used to separate columns.

Here's how you can do it:

import pandas as pd

TESTDATA = """col1;col2;col3
1;4.4;99
2;4.5;200
3;4.7;65
4;3.2;140
"""

df = pd.read_csv(pd.compat.StringIO(TESTDATA), sep=";")

In the above code snippet, we first import the Pandas library using import pandas as pd. Then, we pass our test data string TESTDATA to the pd.compat.StringIO() function to create a file-like object from the string. The sep=";" parameter specifies that the columns are separated by semicolons.

Finally, we use the pd.read_csv() function to read the data from the file-like object and create a Pandas DataFrame named df. And that's it! You now have your test data loaded into a DataFrame and ready to be used.
