hello im Devprintx 😃.

I will start learning programming with you and share with you and help you learn with me step by step ❤️.

1-First we will start with Python 📱.

2-The second will be JavaScript 📱.

I will publish many codes and explanations in the coming days. Share the channel to spread the benefit 📱.

The first thing is the print order.

Executed Code 📱 :

print("hello world")

Output:

hello world

The second thing is the variables.

It represents the closet that keeps things inside it.

Executed Code 📱 :

a = "DevprintX"
print(a)

output :

DevprintX

Ofcourse you can't use any of python keywords as variable names or you will get syntax error like True = 'Yes' it will give you error but you can use yes = True.

You can also use it in a different way.

Executed Code 📱 :

first_name = "DevprintX"
second_name = "Dev"
print(first_name + second_name)

output :

DevprintXDev

To be more organized, clean something small.

first_name = "DevprintX"
second_name = "Dev"
print(first_name + " " +second_name)

output :

DevprintX Dev

This allows us to add space between words.

Also.

first_name = "DevprintX"
print(f"your name is : {first_name}")

output :

your name is DevprintX

f means format Its name in Python is : f-string

Another example 📱:

age = 18
print(f"you are {age} years old")

output :

you are 18 years old

Today's lesson is : Type casting = the process of converting a variatile from one data type to another
str(), int(), float(), bool()

Executed Code 📱 :

name = "DevprintX"
age = 18
price = 10.99
is_student = True

print(type(name))
print(type(age))
print(type(price))
print(type(is_student))

output :

<class 'str'>
<class 'int'>
<class 'float'>
<class 'bool'>

the explanation :

DevprintX is #string (DevprintX)
the nember 18 is #integer (18)
the nember 10.99 is #float (10.99)
True is #boolean (True)

note :

If we put any number or anything literally between quotation marks " "

The type will be (str) #string

Executed Code 📱 :

age = "18"
print(type(age))

output :

<class 'str'>

We can also change the type of anything.

Executed Code 📱 :

number1 = str(18)
number2 = float(18)
number3 = bool(18)

print(type(number1))
print(type(number2))
print(type(number3))

<class 'str'>
<class 'float'>
<class 'bool'>

Although it is an integer, the output came out like this, so we can conclude that we can change the type of anything.

Now we will work with input : Allows us to enter the information ourselves.

Executed Code 📱 :

age = int(input("Enter your age : ")) 
print(f"your age is {age}")

The output will be the number you entered, For example, if we enter 18

your age is  : 18

note : We put int so that the program accepts only correct numbers. For example, if we enter an incorrect name or number, an error will appear.
