Python Read Operation

Python provides built-in functions to read data from a file. Reading from a file refers to extracting information from a file. In this tutorial, we will learn about reading operations in Python.

Syntax

The syntax to read data from a file in Python is:

file_object = open("filename", "r")
file_content = file_object.read()
print(file_content)
file_object.close()

In the above syntax, the 'open()' function is used to open the specific file in a particular mode. The 'r' mode is used to read the data from a file. The 'read()' function is used to read the entire content of the file.

Example

Let's see an example of reading data from a file in Python.

# Opening a file in read mode
file = open("file.txt", "r")

# Reading the contents of the file
file_content = file.read()

# Printing the contents of the file
print(file_content)

# Closing the file
file.close()

Output

The above code will output the entire contents of the file "file.txt" to the console.

Explanation

In the above example, we open the file "file.txt" in read mode using the 'open()' function. Then, we read the contents of the file using the 'read()' function and store them in a variable called 'file_content'. Finally, we print the contents of the file to the console and close the file using the 'close()' function.

Use

Python's read file operation can be used to read various types of files such as text, images, audio, video, etc.

Important Points

• The 'open()' function is used to open files in Python.
• The 'r' mode is used to read the contents of files.
• The 'read()' function is used to read the entire contents of a file.
• It is important to close a file after reading to prevent any data corruption.

Summary

In this tutorial, we have learned about reading operations in Python. We have seen the syntax, example, output, explanation, use, and important points regarding reading data from a file in Python.
