What will happen if you open up a terminal, then type “import this”? In windows: >>> import this C:\Users\darwin>python Python 3.9.12 (main, Apr 4 2022, 05:22:27) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32 Warning: This Python interpreter is in a conda environment, but the environment has not been activated.

Python>>String Interpolation and Formatting
String Interpolation is a process substituting values of variables into placeholders in a string Few methods as follow: a. .format() = is for simple positional formatting that uses to substitute in place of braces {}. Example: >> print (‘Welcome to {}’.format(‘ Linux Tutorials’)) Welcome to Linux Tutorials >> title = “Linux Tutorials” >>> print(‘Welcome to…
Python>>String Methods
Here are some common String Methods or Attributes that you can use in modifying strings. Assuming x is the string: a. x.upper() – converts to upper case > x = ‘Free Linux Tutorials’ >>> x.upper() ‘FREE LINUX TUTORIALS’ >>> print(x) Free Linux Tutorials >>> y = x.upper() >>> print (y) FREE LINUX TUTORIALS b….
Python>>String Concatenation
String concatenation is simply adding strings together. Here are sample String Concatenation: Sample1: >> a = ‘Free’ >>> b = ‘Linux’ >>> c = ‘Tutorials’ >>> a + b + c ‘FreeLinuxTutorials’ >>> d = a + b + c >>> print (d) FreeLinuxTutorials >>> Sample2: >>> a = ‘Welcome’ >>> b = ‘to my’…
Python>>Strings: Indexing and Slicing
I will be showing more examples of indexing and slicing as a form of my practice to familiarize this. From the previous lesson/posts, the syntax for slicing as follows: string[start : end : step] Example1: (Indexing and Slicing in Strings) W r i t e C o d e O n l i n e…
Python>>Data Type:Strings
Strings are text type and are sequences of character data. It is represented by quotation marks, either single or double quotes. Example: “Hello” ‘What is your name?’ >>> “Hello” ‘Hello’ >>> x = ‘What is your name?’ >>> print (x) What is your name? >>> Some key notes: 1.Escape sequences in strings = use backslash…
Python>>Data Type:Float
Floating point number is real numbers with decimal point (.)or fractional part. It can be positive or negative. Example: 5678.90 -2.88 0.99 >>> z = -1.234 >>> type(z) <class ‘float’> Let’s do arithmetic: >>> x = 8+8.1 >>> print (x) 16.1 >>> print (type(x)) <class ‘float’> Some key notes: 1. numbers separated with underscore can…
Python>>Data Type:Integer
Integers or Int are whole numbers without the decimal point or fractional part. It can be positive or negative or zero.It can be binary, octal or hexadecimal values. Let’s do mathematical calculation: Arithmetic operators: addition = + subtraction = – multiplication = * division = / modulus = % exponent = ** floor division…
Basic Data Types in Python
There are few data types in Python namely: integers (int) – numeric type, whole numbers (can be positive or negative), e.g. 1,2,3 floating (float) – numeric type,numbers with decimal point, e.g. 1.1, 2.20, 3.450 complex (complex) – numeric type, real + imaginary,e.g. 5+6q strings (str) – text type, sequences of characters,e.g. “Euan”, “1234” dictionaries (dict)…
The immortal “Hello World”
To test our setup, we will going to run the very simple print code, and there’s no other contents better than the word “Hello World” Our very first code of course: print (‘Hello world’) Note: -it will be inside the open and close parenthesis -can use single or double quote There are few ways (in Window) 1….
