Top 10+ Common Python Commands Every Beginner Should Know

-



Are you new to Python programming? Whether you're starting your coding journey or brushing up on basics, mastering the most common Python commands is essential for writing clean and efficient code. In this post, we'll cover a list of essential Python commands that every beginner should know.

These Python commands form the foundation of any Python script and will help you take your first steps into the world of programming.


---

1. print() – Display Output

The print() function is used to display text or variables to the console.

print("Hello, Python!")


---

2. input() – Take User Input

The input() function allows you to take input from the user.

name = input("Enter your name: ")
print("Welcome,", name)


---

3. len() – Get Length of an Object

Use len() to get the length of a string, list, or other iterable objects.

fruits = ["apple", "banana", "cherry"]
print(len(fruits))


---

4. type() – Check Data Type

The type() function returns the type of a variable or object.

age = 25
print(type(age))  # Output: <class 'int'>


---

5. int(), float(), str() – Type Conversion

Convert values to different data types using these built-in functions.

x = "10"
print(int(x))     # Convert to integer
print(float(x))   # Convert to float
print(str(10))    # Convert to string


---

6. def – Define a Function

Functions help you reuse code. Define them using def.

def greet():
    print("Hello, World!")
greet()


---

7. for – Looping Through Items

The for loop is used to iterate over a sequence.

for i in range(5):
    print(i)


---

8. if – Conditional Statements

Use if, elif, and else to make decisions in your code.

num = 10
if num > 5:
    print("Greater than 5")


---

9. import – Use Python Libraries

Use import to include standard or third-party libraries in your script.

import math
print(math.sqrt(16))


---

10. range() – Generate a Sequence of Numbers

Often used in loops, range() helps you create a sequence of numbers.

for i in range(1, 6):
    print(i)


---

Bonus: while – Another Looping Technique

The while loop runs as long as a condition is True.

i = 1
while i <= 5:
    print(i)
    i += 1


---

Conclusion

These are just a few of the many useful Python commands that can help you build strong foundational skills. As you continue learning, you’ll discover more advanced functions, modules, and libraries to enhance your coding ability.

🌀 SMURF ATTACK 🌀 A smurf attack is a type of denial of service attack in which a system is flooded with spoofed ping messages.This creates high computer network traffic on the victim’s network,which often renders it unresponsive. Smurfingtakes certain well-known facts about Internet Protocol and Internet Control Message Protocol (ICMP)into account.ICMP is used by network administrators to exchange information about network state,and can also be used to ping other nodes to determine their operational status.The smurf program sends a spoofed network packet that contains an ICMP ping.The resulting echo responses to the ping message are directed toward the victim’s IP address.Large number of pings and the resulting echoes can make the network unusable for real traffic

Disclaimer: This tutorial is for educational and ethical hacking purposes only. Unauthorized access to systems is illegal and punishable by law. Always get proper permission before testing. Metasploit is one of the most powerful tools in any ethical hacker’s toolkit. In this guide, we’ll walk through the steps to create a malicious PDF file embedded with a Meterpreter payload using Metasploit. This method is commonly used for penetration testing on Windows systems. --- Step 1: Launch Metasploit Start by opening your terminal and running the Metasploit Framework: msfconsole --- Step 2: Search for an Appropriate Windows PDF Exploit We need an exploit that targets Adobe PDF files on Windows. Use the following command to search Metasploit's database: msf > search type:exploit platform:windows adobe pdf Look for this exploit in the results: exploit/windows/fileformat/adobe_pdf_embedded_exe Select it with the use command: msf > use exploit/windows/fileformat/adobe_pdf_embedded_...

🚩Adware − Adware is software designed to force pre-chosen ads to display on your system. 🚩Attack − An attack is an action that is done on a system to get its access and extract sensitive data. 🚩Back door − A back door, or trap door, is a hidden entry to a computing device or software that bypasses security measures, such as logins and password protections. 🚩Bot − A bot is a program that automates an action so that it can be done repeatedly at a much higher rate for a more sustained period than a human operator could do it. For example, sending HTTP, FTP or Telnet at a higher rate or calling script to create objects at a higher rate. 🚩Botnet − A botnet, also known as zombie army, is a group of computers controlled without their owners’ knowledge. Botnets are used to send spam or make denial of service attacks. 🚩Brute force attack − A brute force attack is an automated and the simplest kind of method to gain access to a system or website. It tries different combinatio...
