String Part 2 in Python3


There is a special character called backslash character, it has a special meaning in strings, it's used to escape the character that follows it to give that character special meaning. The backslash character provide us a new line. So, let's see.



Now, as you can see \n has actually caused the cursor to start on the next line. So, for each one of those \n's we added that actually spit onto a separate line each time we did it.


Now, we'll do the same with tab character.



It's used a standard tab function which you’ve probably seen in a word processor before to tab things out which is a way of sort of organizing things in a certain position.
You can also use that backslash to escape special characters such as quote and double quotes, and that’s useful if you’ve got a string containing both characters.
Let me show the example.



So here, if we are using both single quotes and double quotes in a particular string which you may want to use some time. If started off with this string by saying it’s a single quote, but by putting the backslash in front of the quote you want to use, that actually tells Python, to treat it not as a special command to close the string in this case, but to set the string that can actually be printed out and you can do same as with double quotes.
The string that we split over several lines earlier is not easy to read because of the embedded slash and as you can saw Python allows a string to be split over several lines without doing that by using triple quotes, and the way to do that, we type something like this.



Note : Don’t use four quotes in a row instead of three because that doesn’t work to well and you’ll find that Python gets itself into a little bit of a knot with that and if you’re using the three quotes you need to actually have a space before to make sure you haven’t got four quotes in a row.

String Slicing and Picking sub-string in Python3

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...
