Hello World Program in Python — Python Technical Interview Questions & Answers

Hello World Program in Python

Hello World Program in Python

  • Hello World is the smallest Python program. We don’t write it to impress anyone. We write it to check that Python runs. If this prints, the interpreter works, PATH is fine, and you can learn the next topic. Every bigger script — marks sheet, file reader, Flask app — still starts from print and a .py file.
  • Write print("Hello Python") in hello.py. Quotes must match: "..." or '...'. print sends text to the terminal and then a new line. Unlike Java, there is no class and no public static void main. Freshers waste time searching for main(). It is not required.
  • Let’s do it on the board. Save the file as hello.py — not hello.py.txt. Notepad sometimes hides the real extension. Open a terminal in that folder. Run: python hello.py. On many Windows machines: py hello.py. Output should be exactly Hello Python. If the command is not found, install/PATH is wrong — that is the install topic, not a Python syntax error.
  • After it works, change the string to your name and run again. That tiny change is the first real program. Don’t copy Hello World twenty times without changing anything.
  • Exam: “Write a program to print your name.” Same one line. Say the run command out loud. Mention no class is needed. That scores.
  • Hello World Program in Python — output: Hello Python. Change the string to your name and run again.

Technical Interview Tip: Write print(...) and the exact run command. Say no class is required.
