Introduction to pd.set_option in Python

pd.set_option is a pandas method that allows developers to set global printing options in their data analysis projects. Data Scientists, Machine Learning Engineers, and Researchers can modify the display properties of their data sets to suit their individual needs.

Usage

Here's an example of how to use the pd.set_option function to modify the global display properties of a pandas DataFrame:

import pandas as pd

# Sample DataFrame
df = pd.DataFrame({"Name": ["John", "Sara", "Mike", "Lisa", "David"],
                   "Age": [32, 21, 45, 18, 29],
                   "City": ["New York", "London", "Paris", "Moscow", "Tokyo"],
                   "Country": ["USA", "UK", "France", "Russia", "Japan"]})

# Modifying global display properties
pd.set_option("display.max_rows", None)
pd.set_option("display.max_columns", None)
pd.set_option("display.width", 1000)

# Displaying DataFrame
print(df)

When the above code block is executed, the following output will be produced:

    Name  Age      City Country
0   John   32  New York     USA
1   Sara   21    London      UK
2   Mike   45     Paris  France
3   Lisa   18    Moscow  Russia
4  David   29     Tokyo   Japan

As you can see, the pd.set_option method allows developers to adjust the global display settings of their pandas data frames. In this example, pd.set_option("display.max_rows", None) removes the row limit, pd.set_option("display.max_columns", None) removes the column limit, and pd.set_option("display.width", 1000) increases the maximum display width to 1000.

Conclusion

The pd.set_option method is an essential tool for data analysts and developers who deal with pandas data. It provides great flexibility and ease of use when it comes to displaying large data sets on the screen. By adjusting the global display settings of your data frames, you can customize the output to suit your needs and preferences.
