Basic Python code involves fundamental concepts such as variables, data types, control structures, functions, and basic input/output operations. Below are some examples of basic Python code to demonstrate these concepts.
### 1.
**Hello, World!**
The simplest
Python program that prints text to the console.
```python
print("Hello,
World!")
```
### 2.
**Variables and Data Types**
Python
supports various data types, such as integers, floats, strings, and booleans.
```python
# Integer
age = 25
# Float
height = 5.8
# String
name =
"Alice"
# Boolean
is_student =
True
```
### 3.
**Basic Arithmetic Operations**
You can
perform arithmetic operations like addition, subtraction, multiplication, and
division.
```python
a = 10
b = 5
sum_result =
a + b # 15
difference =
a - b # 5
product = a
* b # 50
quotient = a
/ b # 2.0
```
### 4.
**Control Structures**
Python uses
control structures like `if`, `for`, and `while` loops to control the flow of
the program.
#### If-Else
Statement
```python
number = 10
if number
> 0:
print("Positive number")
elif number
== 0:
print("Zero")
else:
print("Negative number")
```
#### For
Loop
```python
for i in
range(5): # 0 to 4
print(i)
```
#### While
Loop
```python
count = 0
while count
< 5:
print(count)
count += 1
```
### 5.
**Functions**
Functions
allow you to encapsulate code into reusable blocks.
```python
def
greet(name):
return f"Hello, {name}!"
message =
greet("Alice")
print(message)
```
### 6.
**Basic Input/Output**
You can take
input from the user and display output.
```python
# Taking
input
user_name =
input("Enter your name: ")
# Displaying
output
print(f"Hello,
{user_name}!")
```
### 7.
**Lists**
Lists are
used to store multiple items in a single variable.
```python
fruits =
["apple", "banana", "cherry"]
# Accessing
elements
print(fruits[0]) # apple
# Adding an
element
fruits.append("orange")
# Looping
through the list
for fruit in
fruits:
print(fruit)
```
These
examples cover the basics of Python programming. They give you a solid
foundation to build more complex applications as you continue to learn.
