Say Hello to 'hello world' in Python3

Now, start with 'hello world' 

 To get the output in the python shell you can press F5 and then you have to save the file then you get the output.



It is the easiest of the program in python. Print keyword helps to print the output in the screen.
There are a few important basics to understand. So, python has mathematical functions, like round, to round the number of digits after the decimals point, char to convert characters to the numerical representation and many more.
For string you have to provide a value in parenthesis as you saw there in the 'hello world' in parenthesis, it is a string that's why, we actually have to put a single quote to the left and to the right of the string to tell python that this was a string. But we can also put in numerical numbers if we want it to actually be computed by python.

String Slicing and Picking sub-string in Python3

Image
Picking Sub-String Now, we will pick individual character or sub-string from string. So, lets see, You might be thinking, why is that ‘g’, because we specified the third character, so shouldn’t that be counting from left to right, ‘B’ is the first character, ‘e’ is the second and ‘n’ is the third and in actual fact ‘g’ is the fourth character. Now you are thinking then why we say that ‘g’ is the third character. It’s actually usual for programming languages to start counting at zero and not at one. So that tiger zero is ‘B’. So we’ll actually go and see that, So there’s 12 character in ‘Bengal Tiger’, numbered from 0 to 11 and if we try to print 12 number character, then you’ll get an error. The other thing as you can do is count backwards. So, what’s happened is that it started here at position zero and goes to negative one. Negative one goes all to the way to the end of the string and starts counting from end. So we get the letter, which is t...

Integers and Float in Python3

Image
Let’s move on to variable types. Python has several built-in data types. Data types can be classified as numeric, sequences, mapping, files, classes, instances and exceptions. You’ll be introduced to all of these as this tutorial progresses but now, we’ll look at numeric data types and sequence type. String being a sequence type which we’ve looked at before. Integers So, start with the basic data type, its integer. An integer being a whole number, a number that hasn’t got any decimal points.  So, an integer is just a whole number. It’s a number having no fractional part, where as a float is another name for a real number. That is a number having a fractional part after the decimal point. There is a very small number of computer languages that make no distinction between real numbers and integers. In the computers, computations using integers these whole numbers, are significantly faster than using floating point numbers. That’s the reason we are distinguishing bet...

Variable in Python3

Image
The instructions that you typed in will be stored in one area of memory, but also the data that it’s going to work on, the variables that you’ve typed in, will be stored somewhere else in memory. So the variable, the name that assigned is just really a way to give a meaningful name to an area of memory into which we can place certain values. There are few rules to keep in mind when you actually created them. The actual name has to start with either a letter, it could be upper or lower case, or an underscore but we can’t start that with the number. We can use numbers in our variable names, just not as the first letter. Now the other important thing to consider here is that we could type a variable name called ‘Myname’ with uppercase M and that’s different and distinct to lowercase ‘myname’ variable. Now, in terms of the memory allocation, it happens at the point when you’ve initialized it. In other words once you’ve typed in the variable name and put an equal and the...
