Number
The numeric data type is used to store numeric values i.e [0-9]. Python has three numeric data types:
1. Integers
Ex: a = 20
2. Floating Point numbers
Ex: a = 20.0
3. Complex numbers
Ex: a = complex(20,5) # 20+5j
String
A string is a sequence of characters. In python, we can create a string using a single ( ‘ ‘ ) or double quotes (” “). Both are the same in python
str = 'computer engineering' print('str- ', str) # print string print('str[0]-', str[0]) # print 1st char print('str[1:3]-', str[1:3]) # print string from position 1 to 3 print('str[3:]-', str[3:]) # print string starting from 3rd char print('str*2-' , str*2) # print string two times print('str + yes-', str+'yes') # concatenated string
Boolean
It is used to produce values either true or false.
str = "comp eng" b = str.isupper() print(b)
Tuple
A tuple is an immutable Python Object. Immutable python objects mean we cannot alter the contents of a tuple once it is assigned. It is represented by () parenthesis.
tup = (66,99) Tup[0] = 3 #error will be displayed print(tup[0]) print(tup[1])
Set
It is an unordered collection of unique and immutable items. It is represented by {} curly braces.
set1 = {11, 22, 33, 22} print(set1)
Dictionary
It is an unordered collection of items and each item consists of a key and a value.
dict = {'subject' : 'comp eng", 'class' : '11'} print(dict) print( "Subject :", dict["subject"]) print("class :", dict.get('class'))
