#18 python: a closer look at booleans to know whether something gives out a True or False value, we use the in-build bool function. use later on in this post bool(True) >>> True bool("abc") >>> True bool("") >>> False bool([9, 0]) >>> True bool([ ]) >>> False 🧲 use of it let us say you want to do something as long as there are elements in a list nums = [2,2,9] if nums: #if list not empty ... else: #if list empty ...

#16 python: classes 👓 classes are a way to represent real world things. objects have attributes like colour, age, number of parts etc. objects also do actions like move. 📑 in programming classes is like a plan, like we describe how an object is class Bus: wheels = 4 color = "white" def move(self): print("moving") now we create the actual object by toyota_bus = Bus() we can view attributes print(toyota_bus.wheels) >>> 4 toyota_bus.move() >>> moving

4⃣JavaScript ❤️Love it or 🤮hate it, Javascript is one of the most popular languages for creating games. ✅ It naturally works well with HTML and CSS and is well suited for online games. ✅ Javascript can be used on both the back end and front end of web development and has a huge, helpful online community as well as an enormous number of frameworks. ✅ Javascript has proven to be an extremely versatile language, and with the help of libraries can be used for iOS and Android Apps, desktop apps, and on hardware. With many free online tutorials and a massive GitHub presence,✅ Javascript is one of the easiest languages to learn. It can also be used for scripting with Unity3D.

😱 Bëst 4 Game Programming Languages 1⃣ C++ ❤️ ✅The pioneer of modern game programming languages, C++ adds the concept of (OOP) onto its predecessor Most high-end games that you play today depends on C++ codes in one way or the other. Popular gaming consoles such as the ✅ Xbox and PlayStation both utilize this game programming language heavily. ✅C++ is the must-know language if you anticipate yourself developing futuristic games. 2⃣ Java 😍 ✅Java runs on everything, from printers and microwaves to complex video game systems. ✅ It is a very dynamic language with lots of applications, making it seem like a good choice to learn. 🚻 Java is closely related to 👀C++, so learning the two alongside each other would not be difficult. 3⃣C# 😎 ✅ C# is another powerful language with a wide range of applications. It is somewhat easier to pick up then C++ so it could be a better one to learn first. ✅Several factors make C# a great choice for creating games. The first is its XNA framework, from Microsoft, which makes it perfect for making games for Windows or Xbox. ♓️The second is that is integral to game engines such as the popular Unity3D and Xamarin. C# can be used to make games on virtually any platform, including iOS, Android, PlayStation, and Windows related software as mentioned before. 🔅MonoGame can be used to distribute software over most platforms, and this works well with C#. ✅This is one language that opens doors and allows nearly any gamer to enjoy your creation no matter what hardware they use.

#15 python: more on for loop for loops can also be used to generate numbers for i in range(5): print(i) >>> 0 1 2 3 4 it can be controled via range(, , ) for i in range(1, 10, 2): print(i) >>> 1 3 5 7 9

# 14 python: for loops for loops are more convenient 🛢 they can be used to go through lists fruits = ["apple", "orange", "banana"] for i in fruits: print(i) >>> apple orange banana 👉 but the i above is just a variable name, it can be changed to fruit. for fruit in fruits: print(fruit)

#13 python: loops loops go over and over again until you tell it to stop 💿 demo stop = False x = 0 while stop == False: if x == 5: stop = True x += 1 the above program increases x each time but also checks if it equals 5, if so, it changes the condition 💿 breaking out but you can also stop using the word break x = 0 while True: if x == 5: break x += 1 ⚠ infinite loop a while loop can go on inffinitely if the condition is not thoroughly checked while True is an infinite loop

#12 python: parameters in functions here is a function calculating sum def sum(): return 1+2 but that's not useful what if we want 4 and 5? that's why we add parameters def sum(x, y): return x+y print(sum(4,5)) >>> 9 🌙 line example def line(x): m = 2 c = 3 return m*x + c print(line(2)) >>> 7 🌙 without return def fuzzy(s): print(s*3) fuzzy("ab") >>> ababab

#11 python: functions functions allow us to wrap in many lines of codes print(1) print(2) print(3) can be wrapped in def print_all(): print(1) print(2) print(3) so that when you do print_all() it will print 1 2 3 very convenient as you don't have to type those lines each time 🗝 the return keyword return makes a function behave like a value when you return something def something(): return 1 print(something()) >>> 1 these can be assigned to variables x = something() print(x) >>>1

#10 indentations in python python separates block of codes by indentation if x==1: print(2) ❌ if x==1:     print(2) ✔ you can use either tabs or space if you decide 3 space characters, stick to it if x==1:     print(2) else:            print(3) ❌ if x==1:     print(2) else:     print(3) ✔ 🍂 editors nowadays if you press tab, they normally add 4 spaces for you, so, ease and convenience mixed !

#9 python: conditionals 🍏 example x = 5 if x == 5: print("x equals 5") else: print("x does not equal 5") it will output x equals 5 🍏 other operators x = 6 if x > 5: print("x greater than 5") else: print("x less than 5") outputs x greater than 5 🍏 other operators < less than != not equal to >= greater equal to <= less equal to 🍏 smart python if 3

#8 python: more operators 🔰 += x += 1 means x = x + 1 x = 0; x += 1 now x is 1 🔰 -= x = 5 x -= 1 x now 4 🔰 *= x = 5 x *= 4 x now 20 🔰 /= x = 10 x /= 5 x now 2.0 🔰 //= x = 13 x //= 2 x now 6 https://code.dcoder.tech

#7 python: print print is used to output to the screen print(1) >>> 1 print(1,2,3) >>> 1 2 3 print(1, "a") >>> 1 a print(1,2) print(3,4) >>> 1 2 3 4 ⛱ sep print(1,2,3, sep="@") >>> 1@2@3 ⛱ end end specifies which character to put at the end. default is newline print(1,2,3, end="%") print(5,6) >>> 1 2 3%5 6

#6 python: comments comments are used to provide information about the code and are ignored by the interpreter. 🎈 single line comments single line comments start with # # this is a comment example # apples in our basket x = 5 🎈 multiline comments multiline comments are enclosed in """ """ or ''' ''' x = 1 """ this is a comment """ y = 2 🎈 on efficiency single line comments are ignored by the interpreter whereas multiline comments are put in memory. large chuncks of the latter affect efficiency

#5 python: more on strings strings can be like x = "i am here" or x = 'i am here' or multiline x = ''' i am here ''' or x = """ i am here""" ⭐️ use of mixing " and ' if you have like *i didn't* you cannot wrap it with ' like x = 'i didn't' as the interpreter will be confused you do it like x = "i didn't " same to store " x = 'a " a' ⭐️ string multiplication "a" * 4 gives aaaa ⭐️ string addition (concatenation) "ab" + "c" gives "abc"
