If you are a programmer and you are looking for work right now you probably know that Python is one of the most sought after job skills for developers today. And with the rise of Machine Learning and AI, demand for Python programmers is just increasing.<\/p>\n
Chances are that you go about learning a new language by diving straight into some project and trying to figure it out as you go. That’s a great way to learn, We’re big fans of practical application. It can also be a frustrating way to learn because you keep hitting walls when things don’t go your way.\u00a0That’s why we give you 5 survival tips to make your transition to Python less frustrating.<\/p>\n
Python is known for its simple syntax, in fact a central “pythonic” philosophy is to not use any unnecessary characters. If \u00a0you are coming from another programming language such as Java or any C dialect you will have imprinted in your spine that every line must end with a semicolon. In Python you can\u00a0<\/em>still do that, it will work. But it is not very pythonic.<\/p>\n There are also no curly brackets. There is no need for them because you must always indent your code, which brings us to the next point.<\/p>\n <\/p>\n There are two types of programmers in this world. Those who format their code well, and those who don’t. Python enforces us all into good habits, your code simply will not work if you do not indent properly. How to conform? Simply follow that little voice in your head that says “you should have indented this part”.<\/p>\n Python is dynamically typed, which means you generally do not need to worry about what type your variables are. In fact you can even change them to another type during runtime. Your variables are declared when you assign them and Python figures out the type all by itself. So you can do things like this:<\/p>\n In the above example a starts out as a str<\/strong>, and is then dynamically changed to an int<\/strong> when it gets assigned the value ‘1 + b<\/strong>‘ (which equals 3).<\/p>\n Functions are defined like this:<\/p>\n Remember how we said Python does not like unnecessary characters and enforces indents? This makes function definitions really simple. Just a ‘def’ and a colon and any arguments in parentheses. No curly brackets, no “private static void blah blah”. Just define your function and un-indent when your function is \u00a0finished.<\/p>\n The strangest thing about Python function definitions is that the first argument is always “self<\/strong>“. You can call it what you want, but it will always be a\u00a0reference to the current instance of the class. If the first argument is always self, why do we have to type it? 2. Forced Indents<\/h4>\n
3. Dynamic Types – Nothing To Declare<\/h4>\n
>>> a = \"Hello I'm a String\"\r\n>>> b = 2\r\n\r\n>>> type(a)\r\n<type 'str'>\r\n>>> type(b)\r\n<type 'int'>\r\n\r\n>>> a = 1 + b\r\n>>> type(a)\r\n<type 'int'>\r\n\r\n>>> a\r\n3<\/pre>\n
4. Function definition<\/h4>\n
def my_function(self, something):\r\n print(something)<\/pre>\n
