List is similar to an array in JavaScript.Example:[0, 1, 2, 3, 4, 5] # all are the same data types - a list of numbers['Banana', 'Orange', 'Mango', 'Avocado'] # all the same data types - a list of strings (fruits)['Finland','Estonia', 'Sweden','Norway'] # all the same data types - a list of strings (countries)['Banana', 10, False, 9.81] # different data types in the list - string, integer, boolean and floatDictionaryA Python dictionary object is an unordered collection of data in a key value pair format.Example:{'first_name':'Asabeneh','last_name':'Yetayeh','country':'Finland', 'age':250, 'is_married':True,'skills':['JS', 'React', 'Node', 'Python']}TupleA tuple is an ordered collection of different data types like list but tuples can not be modified once they are created. They are immutable.Example:('Asabeneh', 'Pawel', 'Brook', 'Abraham', 'Lidiya') # Names('Earth', 'Jupiter', 'Neptune', 'Mars', 'Venus', 'Saturn', 'Uranus', 'Mercury') # planetsSetA set is a collection of data types similar to list and tuple. Unlike list and tuple, set is not an ordered collection of items. Like in Mathematics, set in Python stores only unique items.In later sections, we will go in detail about each and every Python data type.Example:{2, 4, 3, 5}{3.14, 9.81, 2.7} # order is not important in setChecking Data typesTo check the data type of certain data/variable we use the type function. In the following terminal you will see different python data types:Python FileFirst open your project folder, 30DaysOfPython. If you don't have this folder, create a folder name called 30DaysOfPython. Inside this folder, create a file called helloworld.py. Now, let's do what we did on python interactive shell using visual studio code.The Python interactive shell was printing without using print but on visual studio code to see our result we should use a built in function _print(). The print() built-in function takes one or more arguments as follows print('arument1', 'argument2', 'argument3'). See the examples below.Example:The file name is helloworld.py# Day 1 - 30DaysOfPython Challengeprint(2 + 3) # addition(+)print(3 - 1) # subtraction(-)print(2 * 3) # multiplication(*)print(3 / 2) # division(/)print(3 ** 2) # exponential(**)print(3 % 2) # modulus(%)print(3 // 2) # Floor division operator(//)# Checking data typesprint(type(10)) # Intprint(type(3.14)) # Floatprint(type(1 + 3j)) # Complex numberprint(type('Asabeneh')) # Stringprint(type([1, 2, 3])) # Listprint(type({'name':'Asabeneh'})) # Dictionaryprint(type({9.8, 3.14, 2.7})) # Setprint(type((9.8, 3.14, 2.7))) # TupleTo run the python file check the image below. You can run the python file either by running the green button on Visual Studio Code or by typing python helloworld.py in the terminal .🌕 You are amazing. You have just completed day 1 challenge and you are on your way to greatness. Now do some exercises for your brain and muscles.💻 Exercises - Day 1Exercise: Level 1Check the python version you are usingOpen the python interactive shell and do the following operations. The operands are 3 and 4.addition(+)subtraction(-)multiplication(*)modulus(%)division(/)exponential(**)floor. Learn Python for free. An introduction to Python Programming .

Portable Python environment that can be used across different Windows systems. The snippet demonstrates the process of setting up a portable Python environment that allows for incredible flexibility, requiring no system-wide changes or installations.Bonus One-Liner Method 5: Using the Windows Command Line For users who prefer a quick one-liner, Python can also be installed directly from the Windows command line using a simple command if you have the curl tool installed.Here’s an example:curl -o python-installer.exe && start python-installer.exeThe output is that the Python installer for version 3.x will be downloaded and immediately executed. This example fetches the Python installer using curl and executes it, minimizing the interaction required to get Python installed.Summary/Discussion Method 1: Official Python Installer. User-friendly GUI. Adjustable settings. Manual updates required. Method 2: Chocolatey. Automated installation. Good for developers. Needs familiarity with CLI. Method 3: Microsoft Store. Simple and maintains updates. Limited availability for older Windows versions. Method 4: Portable Python. Flexible and mobile. Disconnected from system updates. Bonus Method 5: Windows Command Line. Quick one-liner. Requires initial setup of curl.Comments
