In this lecture we will learn:
- How operations are performed in Python language?
- Different types of Arithmetic operations
- What are strings?
- How strings are used in Python?
- Function in a Python
- Concatenation and Repetition of Strings
- New line character and Raw string
#1
- We will the Python IDLE in this tutorial.
- The language that the computer understands is Binary Code i.e, 0 and 1.
- We use a programming language to write code, which is neither a binary language nor English.
- Programming language has its own protocols and grammar which we use.
- We will write code in a programming language say Python and then it will convert into a binary format that the computer will understand.
- We can perform several operations using Python language.
#2
- Starting with operations like Addition, Subtraction, Multiplication, and Division.
- We do addition, subtraction and multiplication with integer values, and then it gives us answers also in integer data type.
- But when performing division with integer values then it gives us an answer in float data type.
- Float stands for Floating Point Representation.
- When we divide two integer values then it might be possible that the answer can in decimal.
e.g., 5/2 = 2.5
- As the interpreter wants to give you an exact answer for the division also, it will return it in float.
- If you want to get only the quotient part or the integer part of the answer and want to neglect the decimal value, it can be done with the help of (//).
- // (double slash) is used for division when you want to return only an integer value in the answer.
- // is also called Integer Division or Floor Division.
- We can multiple operations in a single statement as well.
- We need to follow the proper syntax for the programming language.
- If we apply an operation but do not give operands, then it will give an error.
8+9- = Error
- We can also apply BODMASS rules of mathematics to perform operations.
- Double asterisks (**) is used to find the power of a number.
number ** power = 2**3 = 2*2*2
- To get the remainder, we use the modulus operator (%).
#3
- String is a combination of characters like "KZbin", "Camera", "Telusko", "Python", etc., all are strings.
- Whenever we use strings, we need to use double quotes(" ") or single quotes(' ') with it in python.
- If you back-slash(\) to tell the python to ignore the special meaning of that double and single quotes.
- If you use a back-slash before a single or double quotes then the quote is also treated as a simple character.
#4
- Function is a set of tasks that can be done. We need to call functions. There are several functions in Python like the print() function.
- Round brackets are used with a function to pass a parameter in it.
- We can define our own functions as well.
#5
- Concatenation is used to combine two things like we can convert two strings into one using concatenation.
- Concatenation is done using the (+) operator.
e.g., 'navin' + 'navin'
- Repetition is used to print a single value multiple times like we can print a string like "Navin" multiple times.
- Repetition is done using the (*) operator.
e.g., 'navin' * 3
#6
- (
) has a special meaning in Python. It is used to enter a new line.
- To print the original string or to neglect the meaning of
, we have to use a Raw String.
- Raw string is a string that returns it as it is without making any changes to it.
- We have to specify (r) before the quote to print the same string that is present inside the quotes.
