How to import a text file in Python

by

The open() function can be used to open a text file in read mode so that its contents can be viewed using read(), readline(), or readlines().

The text file can then be opened in write mode using open(), and data can be written there using the write() method.

The open() function can be used to open a file. Two arguments are required: the file path and the desired mode of opening the file (read, write, append, etc.).

We have multiple options for reading the file’s content once it has been opened.

The read(), readline(), and readlines() methods are the most often utilized ones.

Open a file in write mode ("w") or append mode ("a") in order to write data to it.

The file’s current content is overwritten when in write mode. New content is appended to the end of the file when it is in append mode.

We can take the following actions to import local files into Python using the Pandas library:

Use pip install pandas to install Pandas.

Use import pandas as pd to import the Pandas library.

To import the file, specify its path and use the relevant Pandas function (pd.read_csv() for CSV files, pd.read_excel() for Excel files).

We can take the following actions to import local files into Python using the NumPy library:

Use pip install numpy to install NumPy.

import numpy as np is the command to import the NumPy library.

To import the file, specify its path and use NumPy’s loadtxt() or genfromtxt() functions.

Understanding file paths and directories is crucial when importing local files into Python in order to find and access the desired files efficiently.

A file path is a string that indicates where a file or directory is located within the file system.

A relative path indicates the path with respect to the current working directory, whereas an absolute path indicates the entire path beginning at the root directory.

The Python os module, which offers methods like os.getcwd() to obtain the current working directory and os.chdir() to modify it, can be used to navigate directories.

Python offers several built-in functions for reading text files, such as open(), and specialized libraries like Pandas for importing a variety of file formats, including CSV, Excel, JSON, and more.

Developers can quickly import and incorporate local files for data exploration, analysis, and visualization into their projects by utilizing Python’s capabilities and its many libraries.

Now let’s see how to import a text file into Pycharm in Python.

  1. Choose by right-clicking on a data source or a schema in the Database tool window.

  2. Locate the SQL file you wish to run in the newly opened file browser window, then click Open.

  3. Select by performing a right-click on a table or schema in the Database tool window.

  4. Provide the destination table’s settings and data mapping information in the Import ‘table_name’ Table dialog.

  5. Enter the destination table’s settings and data mapping information in this dialog.

  6. Provide the destination table’s settings and data mapping information in the Import ‘table_name’ Table dialog.

  7. Provide the destination table’s settings and data mapping information in the Import ‘table_name’ Table dialog.
