Here are some basic Python examples to get you started with coding:
This is the traditional first program that you write when learning a new programming language. To print "Hello, World!" in Python, you can use the `print()` function:
print("Hello, World!")
In Python, you can use variables to store values. To create a variable, you just need to give it a name and assign a value to it using the assignment operator (`=`). For example:
message = "Hello, World!"
print(message)
You can also assign a value to a variable and then change its value later:
message = "Hello, World!"
print(message)
message = "Goodbye, World!"
print(message)
Python has several built-in data types, including integers, floating point numbers, strings, and boolean values.
# integers
x = 10
y = -5
# floating point numbers
a = 3.14
b = -2.718
# strings
name = "Alice"
greeting = "Hello, " + name
# boolean values
is_cool = True
is_warm = False
Python supports various operators, such as arithmetic operators (e.g., +, -, *, /), comparison operators (e.g., ==, !=, >, <), and logical operators (e.g., and, or, not).
# arithmetic operators
x = 3 + 4
y = 5 - 2
z = 4 * 3
w = 6 / 2
# comparison operators
a = 3 > 4
b = 5 == 5
c = 6 != 10
# logical operators
is_cold = True
is_sunny = False
is_nice = is_cold and is_sunny
Python has several control structures that allow you to control the flow of your program, such as `if` statements, `for` loops, and `while` loops.
# if statement
temperature = 30
if temperature > 25:
print("It's hot outside.")
# for loop
for i in range(5):
print(i)
# while loop
count = 0
while count < 5:
print(count)
count += 1
Python allows you to define your own functions, which can be used to perform specific tasks.
def greet(name):
print("Hello, " + name + "!")
greet("Alice")
greet("Bob")
