The most useful way to interact with Python is with print() it lets you interact with the console as it shows u what is going on, i recommend copying this code then interacting with it to see what you can achieve or just read it and try yourself, there is extra documentation i found useful at the bottom
'''As you might see now the pseudo tutorial will be all written in Python This way you could just copy the code and test yourself''' #The most basic thing we learn to print in Python is #The one and only, the world famous Hello world print ("Hello world") '''In python 3.something print works as a function. It takes one argument which can be a string like Hello world or a variable as it could be''' string_x = "Hello world" print (string_x) #Prints Hello World #[Note for Myself add a link to Basic types and their use] '''As you can see im jumping from single line comments to multi when its needed, "...because i can"-Ken Bauer''' #You can print to the screen more types like integers or floats int_x = 10 #Prints 10 float_x = 20.0 #Prints 20.0 #NOTE we are not using the same x or something each something_x #Its used only for names [Note for self, add tips on calling things] print (int_x) #Prints the int_x value print (float_x) #Prints the float_x value '''Sometimes you want to print something more than just the value of something thats when concatenating comes useful''' hello = "Hola" world = "Mundo" print (hello + world) #This is a bit problematic since it Prints #HolaMundo together so we need print (hello + " " + world ) '''If we would need to print a string with a lots of variebles in itwould get tedious over time to do variable + " " + variable + " " + variable... and so on, in this cases we could use string formatting''' #Watch dis string boi #Copy this code if you want and test string formatting yourself #(I could use input() but well this is a output tutorial) name = "Juan" lastName = "Quirino" ageInYears = 18 fingersInLeftHand = 5.1 gender = "Male" '''So now we have 5 variables, i would like to write a line of code that is reusable and describes the user this is when string formatting comes useful''' #So we can have this print ("Hello my name is %s %s, i am %s years old im a %s and i \ have %s fingers in my left hand") % \ (name,lastName,ageInYears,gender,fingersInLeftHand) #Instead of this #Plus we need to use str() to convert to string print ("Hello my name is " + name + ", i am " + \ str(ageInYears) + " old im a " + gender + " and i have " + \ str(fingersInLeftHand) + " in my left hand") #As you can see im using a \ in my print statement # \ Serves to continue a statement on next line without #Breaking the statement

Aparently “string”.format() is the thing now, but the oldie still works
