Syntax

import pandas as pd

# basic syntax for creating a Pandas dataframe
df = pd.DataFrame(data, columns=['column1', 'column2', ...])

Example

import pandas as pd

data = {'Name': ['John', 'Sam', 'Alex', 'Luke'],
        'Age': [28, 23, 31, 27],
        'City': ['New York', 'London', 'Paris', 'Sydney']}

df = pd.DataFrame(data, columns=['Name', 'Age', 'City'])

Output

    Name  Age      City
0   John   28  New York
1    Sam   23    London
2   Alex   31     Paris
3   Luke   27    Sydney

Explanation

Pandas is a popular data manipulation library in Python that is used for data processing, cleaning, filtering, and analysis. Data in pandas is usually stored in a tabular format as a Pandas dataframe.

The basic syntax for creating a Pandas dataframe is to pass a dictionary or a list of dictionaries to the pd.DataFrame() function and specify column names.

In the above example, we create a Pandas dataframe using a dictionary that contains data for four people with their names, ages, and cities. We specify the column names in a list and pass it to the columns parameter.

Use

Pandas dataframes are widely used for data processing and analysis tasks. They can be used for cleaning messy data, performing analysis and visualization, and filtering data based on specific criteria.
