Python is one of the easiest and most fun programming languages to learn. 🎉
If you are a beginner, knowing the right commands can save time and help you code smarter.
In this guide, we will explore 20 essential Python commands. You'll see simple examples, real-life analogies, and step-by-step explanations. By the end, you'll feel confident to start coding and creating projects.
Let's dive in and unlock your Python superpowers! ⚡
1. print() – Show Messages on Screen
The print() command displays text or numbers.
Think of it like talking to your computer.
print("Hello, PyVerse!")
print(5 + 3)Why it matters: It helps you see results and debug your code.
2. input() – Ask the User Questions
Use input() to get information from someone using your program.
name = input("What is your name? ")
print("Hello, " + name + "!")Tip: Always store input in a variable to use later.
3. len() – Find the Length
len() tells you how long a string, list, or other collection is.
fruit = "apple"
print(len(fruit)) # Output: 5Think of it like counting the letters or items. 📝
4. type() – Check the Data Type
type() shows what kind of data you are working with.
age = 12
print(type(age)) # Output: <class 'int'>Why it matters: Helps prevent errors in your program.
5. int(), float(), str() – Change Data Types
Convert numbers and text easily.
num = input("Enter a number: ")
num = int(num)
print(num + 5)Tip: Python is strict about types, so conversion is important.
6. if, elif, else – Make Decisions
Control the flow of your program based on conditions.
score = 75
if score >= 90:
print("A+")
elif score >= 60:
print("Pass")
else:
print("Fail")Analogy: Like choosing an umbrella if it rains, or sunglasses if sunny. ☔😎
7. for Loop – Repeat Actions
for loops help you repeat tasks automatically.
for i in range(5):
print("Python is fun!", i)Tip: range(5) goes from 0 to 4.
8. while Loop – Keep Going Until a Condition
while loops run as long as a condition is True.
count = 0
while count < 3:
print("Learning Python!")
count += 1Caution: Avoid infinite loops—they never stop! 🔁
9. list – Store Multiple Items
Lists are like boxes to keep multiple values.
fruits = ["apple", "banana", "cherry"]
print(fruits[0]) # Output: appleTip: Indexing starts from 0.
10. append() – Add Items to a List
Easily add items to your lists.
fruits.append("orange")
print(fruits)Why it matters: Helps manage dynamic data.
11. remove() – Delete Items from a List
Remove items you don't need anymore.
fruits.remove("banana")
print(fruits)12. range() – Generate Numbers Easily
range() works great with loops.
for i in range(1, 6):
print(i)Tip: Starts at 1, ends at 5 (exclusive).
13. import – Use Extra Tools
Python has lots of modules to extend functionality.
import math
print(math.sqrt(16)) # Output: 4.0Analogy: Like borrowing a toolbox for special tasks 🧰
14. help() – Learn About Commands
help() teaches you how Python commands work.
help(len)Tip: Perfect for beginners learning new commands.
15. min() and max() – Find Smallest or Largest
Quickly get the smallest or largest number in a list.
scores = [70, 85, 90]
print(min(scores)) # 70
print(max(scores)) # 9016. sum() – Add Numbers in a List
numbers = [1, 2, 3, 4]
print(sum(numbers)) # Output: 10Tip: Save time instead of adding manually.
17. sorted() – Organize Data
Sort numbers or words easily.
nums = [3, 1, 4, 2]
print(sorted(nums)) # Output: [1, 2, 3, 4]18. upper() and lower() – Change Text Case
name = "PyVerse"
print(name.upper()) # PYVERSE
print(name.lower()) # pyverseFun tip: Great for standardizing input!
19. count() – Count Occurrences
See how many times an item appears in a list or string.
text = "python python python"
print(text.count("python")) # Output: 320. split() – Break Text into Pieces
sentence = "I love coding"
words = sentence.split()
print(words) # ['I', 'love', 'coding']Why it matters: Makes text easier to handle.
