Welcome to this tutorial where we are going to explore an essential and useful aspect of Python programming. I am going to let you know how to read input from redirected stdin in Python.
Below are given the steps to achieve our task…
Step 1: Importing the Necessary Module
Begin by importing the sys module, which provides access to Python’s system-specific parameters and functions.
import sys
Step 2: Setting Up the Input Reading Loop
Establish a loop to efficiently process lines of input from the redirected stdin. This loop allows your script to systematically handle each line of data.
for line in sys.stdin:
# Process each line as needed
print("Input:", line.strip())
Step 3: Running the Script with Redirected Input
Now we have to save our script and execute it in the command line while redirecting input from a file. This practice simulates a scenario where your script interacts with external data. Below is given how to perform this:
python script.py < input.txt
Step 4: Observing the Script in Action
Witness as your script gracefully reads and processes lines from input.txt, demonstrating a structured and effective approach to handling redirected input.
Step 5: Experimentation and Customization
To enhance your understanding, feel free to experiment with various input files. This step allows you to adapt the script to different scenarios and reinforces the principles of redirected input. It will help improving your programming skill as a Python developer.
Congratulations! We have successfully been able to process the reading of redirected input in Python, a fundamental skill for building robust and versatile scripts. Continue honing your Python skills and exploring additional functionalities for an even more sophisticated coding experience.
