Python for Beginners - Learn Python in 1 Hour
Python Programming Tutorial
In this Python lesson, you'll learn everything you need to start programming in Python.
This tutorial is perfect for data science, machine learning, and web development. No
prior knowledge in Python or programming is required as everything will be taught
from scratch.
What is Python?
Python is a multipurpose programming language that can be used for a variety of
different tasks, such as automation, web development, and data science.
• You can use Python in automation to automate repetitive tasks and save time
and increase productivity.
• You need to install a code editor to write your own Python code.
• You can build amazing websites powered by Python.
Now let's start coding!
age = 30
print(age)
price = 19.95
print(price)
Declare and Use Variables in Python
Here's a little exercise for you: imagine we want to write a program for a hospital, so
we're going to check in a patient named John Smith. He's 20 years old and is a new
patient. Give yourself a task like this and run the output.
Receiving User Input in Python
In Python, we have a built-in function called input() that we use to read a value from
the terminal window. We can add a string argument to the function to prompt the user
for input.
Let's write a simple program to demonstrate this:
name = input("What is your name? ")print("Hello, " + name)
When we run this program, it will prompt the user to input their name. Once a value is
entered, the program will print the greeting message with the input value.
, Data Types in Python
There are three main data types in Python: numbers, strings, and booleans.
• Numbers - This includes integers and floating-point numbers.
• Strings - This includes textual data.
• Booleans - This includes True and False values.
Converting Data Types in Python
Python has several built-in functions for converting the types of our variables. For
example, we have the int() function for converting a value to an integer:
birth_year = "1982"age = 2020 - int(birth_year)print("You
are " + str(age) + " years old.")
In the above example, we use the int() function to convert the birth_year string
to an integer so we can subtract it from the current year.
We also have the float() function for converting a value to a float:
num = "10.5"float_num = float(num)print(float_num)
In the above example, we use the float() function to convert the num string to a
floating point number.
Type Conversion in Python
In programming languages like Python, there are times when you need to convert a
variable from one type to another. In this leeson, you’ll learn a bunch of cool things you
can do with strings using Python for beginners.
In Python, the index of the first character in a string is 0. So, when we run this program,
you're going to see 1 on the terminal because the index is 1.
print("Hello World"[1]) # Output: e
The float function is used to convert a string to a float value.
first = float(input("Enter the first number: "))
We can also change this expression to first + second , which is another way to
write this piece of code.
The lower method is used to convert a string to lowercase or to find a character or a
sequence of characters.
