Introduction to python for beginners

Data Types in Python:

Python has various built-in data types. Some common ones are:

- *int*: For integers (e.g., 1, -3, 100)

- *float*: For floating-point numbers (e.g., 3.14, -0.001)

- *str*: For strings (e.g., "Hello", "Python")

- *bool*: For boolean values (True or False)

Type Checking:

You can use the `type()` function to check the type of a variable.

Ex:

a=10

print(type(a))#output:<class 'int'>

 Type Conversion:

Python allows you to convert between data types using functions like `int()`, `float()`, `str()`, etc.

Ex:

x = "10"  # x is a string

y = int(x)  # Convert string to integer

z = float(y)  # Convert integer to float

print(z)  # Output: 10.0

Assigning Values to Multiple Variables:

Python allows you to assign values to multiple variables in a single line.

Ex:

x, y, z = 10, 20, 30

print(x)  # Output: 10

print(y)  # Output: 20

print(z)  # Output: 30

You can also assign the same value to multiple variables in one line:

Ex:

x = y = z = 100

print(x, y, z)  # Output: 100 100 100

Variable Reassignment:

You can change the value of a variable at any point in your program.

Ex:

x = 5

print(x)  # Output: 5

x = 10

print(x)  # Output: 10

Arithmetic Operators:

Python supports basic arithmetic operations like addition, subtraction, multiplication, division, and more.

Common Operators:

- `+` (Addition)

- `-` (Subtraction)

- `*` (Multiplication)

- `/` (Division)

- `//` (Floor Division)

- `%` (Modulus)

- `**` (Exponentiation)

Ex:

a = 10

b = 3

print(a + b)  # Output: 13

print(a - b)  # Output: 7

print(a * b)  # Output: 30

print(a / b)  # Output: 3.3333...

print(a // b)  # Output: 3 (Floor Division)

print(a % b)  # Output: 1 (Modulus)

print(a ** b)  # Output: 1000 (Exponentiation)
