Binary(0000–1111) number in Python
To access binary value in python you need to put keyword 0b___ and values for binary code
#Direct accessing of binary values
print(0b101)
print(0b1010)#Accessing and converting binary to integer values
aa = int(0b111)
print(aa)#--Output--
5

7
Octal(00–07 10–17) number in Python
To access octal value in python you need to put keyword 0o___ and values for octal code
#Direct accessing of octal values
print(0o03)
print(0o07)#Accessing and converting octal to integer values
ab = int(0o11)
ac = int(0o15)
print(ab)
print(ac)#--Output--

Hexa(00–07 a–e) number in Python
To access hexa-decimal value in python you need to put keyword 0x___ and values for hexa code
#Direct accessing of hexa values
print(0x01)
print(0x06)#Accessing and converting octal to hexa values
ad= int(0xa)
ae= int(0xe)
af= int(0x7)
print(ad)
print(ae)
print(af)
#--Output--

Type conversion of Python Numbers
On below we are gonna to convert one format of code to another.
#Converting floating value to integer value
a=10.5
b=int(a)
print(b)#Converting integer value to floating value
c=125
d=float(c)
print(d)#Converting through operation
e=float(c/a)
f = int(c/a)
print(e)
print(f)#Converting integer value to binary, octal and hexa-decimal value
g=5
h=6
i=7
print(bin(g))
print(oct(h))
print(hex(i))#--Output--
10
125.0
11.904761904761905

0b101
0o6
0x7
Assignment operations in Python
The result of assignment operations will be in Boolean format.
a=9
b=7
#You can change the value a=9 and b=9
print(a>b)
print(a<b)
print(a>=b)
print(a<=b)
print(a!=b)
print(a==b)
print(a is b)
print(a is not b)#--Output--
True
False
True
False
True
False
False
True
Random Function in Python
You can also create random number using Random function
Note: you need to import that module.
import random
#Print random number
print(random.random())#Print random number with range of 0 - 25
print(random.randrange(0,25))#Print random number multiplying by 10
print(random.random()*10)#Print random number multiplying by 10 and type conversion
print(int(random.random()*10))#--Output--
0.7850906069113407

print(math.ceil(9.99))
print(math.floor(10.02))
print(math.floor(9.99))
print(round(10.02))
print(round(9.99))
print(round(3.1417326,3))#Finding power
print(math.pow(5,5))#Finding square root

Python String
Strings is are collection of unicode character that are enclosed in single quotation(‘’) or double quotation(“”)
a=”Naren”
b=’Naren’
#c=’Naren” Wrong format
print(a,b)#Using quotation inside quotation
print(‘Hello,”Good Morning”’)
print(“Hello,’Good Morning’”)
# print(“hello”Everyone””) Wrong format#--Output--
Naren Naren
Hello,"Good Morning"
Hello,'Good Morning'
String Querying
c=”Naren”
print(c)
#To select that particular value
print(c[0])
print(c[1])#To select within limit
print(c[0:2])#[:6] from start to 6
#[3:] from 3 to rest value
print(c[:3])
print(c[2:])#To print all values
print(c[:])#--Output--
Naren
N
a
Na
Nar
ren
Naren
String Concatination
Joining of two or more strings are string concatination
aa=”Hello”
ab=”Everyone”
print(aa+ab)
print(aa+” “+ab)
ac=aa+” “+ab
print(ac)#--Output--
HelloEveryone
Hello Everyone
Hello Everyone
String Output Methods in Python
aa=”Hello”
ab=”Everyone”
ac="Hello Everyone"
#Direct printing variable
print(ac)#Using normal output method
print(“The concatination of aa and ab is “,ac)#Using format method
print(“{},Have a nice day”.format(ac))#Using f string method
print(f”String concatination is {ac}”)
message = (f”{aa},” f”{ab}.”)
print(message)#--Output--
Hello Everyone
The concatination of aa and ab is Hello Everyone
Hello Everyone,Have a nice day
String concatination is Hello Everyone
Hello,Everyone.
The / command
#Use single quot using \'
ba = ‘how you doi\’n ‘
print(ba)#New line \n
bb = ‘how \n you doi\’n ‘
print(bb)#Tab space \t
bc = ‘how \t\t you doi\’n’
print(bc)#Back space \b
bd = ‘how \b\b\byou doi\’n’
print(bd)#--Output--how you doi'n
how
you doi'n
how you doi'n
hoyou doi'n
The String Methods
da = “hello world”#Upper case, Lower case & Title
print(da.upper())
print(da.lower())
print(da.title())#To find length
print(len(da))#To find length
print(da.find(‘wor’))#To split element
print(da.split(‘ ‘))#Replace the element
print(da.replace(‘hello’, ‘hola’))#Join element
print(‘+’.join(da))#Strip element
db = “ hello space “
print(db)
print(db.strip())#--Output--HELLO WORLD
hello world
Hello World

['hello', 'world']
hola world
h+e+l+l+o+ +w+o+r+l+d
hello space
hello space
