How to use PyCharm to read data

Reading data in PyCharm is an intuitive process , which can be easily done using its built-in tools and libraries. The following steps describe the two most common methods of reading data:

Reading data from a CSV file using Pandas

1. Import the Pandas library:

   import pandas as pd

2. Use the read_csv() method to read data:

   data = pd.read_csv('data.csv')

3. After loading the data, you can use various methods of Pandas to process and analyze data.

Read data from text files using NumPy

1. Import the NumPy library:

   import numpy as np

2. Read data using the loadtxt() method:

   data = np.loadtxt('data.txt')

3. NumPy arrays provide a wide range of functions for data processing and manipulation.

Other data sources

In addition to CSV and text files, PyCharm also supports reading data from other data sources, such as:

• JSON
• Excel file
• SQL database

You can use PyCharm's built-in tools (such as the "Open File" dialog box) or third-party libraries (such as SQLAlchemy) to read these data sources.

Example

Here is an example code for reading data from a CSV file using Pandas:

import pandas as pd

data = pd.read_csv('sales_data.csv')

print(data.head())

This will print the first 5 rows of the data frame , allowing you to preview the data.
