Let’s dive into the basics of Python programming. Feel free to copy and paste this guide to get started!
—
1. Setting up Python:
– Download and install Python from [python.org](https://www.python.org/).
– Verify installation using
in your command prompt or terminal.
2. Your First Python Program:
– Basic structure:
displays text.
3. Variables and Data Types:
Code:
name = "John"
age = 25
height = 1.75
– Variables store data; types include strings, integers, and floats.
4. Control Flow:
Code:
if age >= 18:
print("You are an adult.")
else:
print("You are a minor.")
– Learn the
statement for decision-making.
5. Loops:
Code:
for i in range(5):
print(i)
– The
loop iterates through a sequence (0 to 4).
6. Functions:
Code:
def greet(name):
print("Hello, " + name + "!")
greet("Alice")
– Functions encapsulate code for reuse.
7. Lists:
Code:
fruits = ["apple", "orange", "banana"]
print(fruits[1])
– Lists hold multiple items; indexing starts at 0.
8. Dictionaries:
Code:
person = {"name": "Bob", "age": 30}
print(person["age"])
– Dictionaries store key-value pairs.
9. File Handling:
Code:
file = open("example.txt", "w")
file.write("Hello, file!")
file.close()
– Basic file I/O operations.
