Type Conversion

Python defines type conversion functions to directly convert one data type to another which is useful in day to day and competitive programming.

Example 1 :

#int(a,base) : This function converts any data type to integer. 
#‘Base’ specifies the base in which string is if data type is string.
# initializing string 
s = "10010"  
# printing string converting to int base 2 
c = int(s,2) 
print ("After converting to integer base 2 : ", c)  

After converting to integer base 2 : 18

Example 2:

#float() -> This function is used to convert any data type to a floating point number
e = float(s) 
print ("After converting to float : ", e)

After converting to float : 10010.0

Example 3:

#tuple() -> This function is used to convert to a tuple.    
#set() -> This function returns the type after converting to set.   
#list() -> This function is used to convert any data type to a list type.
# initializing string 
s = 'python' 
# printing string converting to tuple 
c = tuple(s) 
print ("After converting string to tuple : ",c)    
# printing string converting to set 
c = set(s) 
print ("After converting string to set : ",c)   
# printing string converting to list 
c = list(s) 
print ("After converting string to list : ",c) 

After converting string to tuple : ('p', 'y', 't', 'h', 'o', 'n')

After converting string to set : {'p', 'n', 'y', 'o', 't', 'h'}

After converting string to list : ['p', 'y', 't', 'h', 'o', 'n']

Example 4:

#dict() -> This function is used to convert a tuple of order (key,value) into a dictionary.
#str() -> Used to convert integer into a string.
#complex(real,imag) -> This function converts real numbers to complex(real,imag) number.
# initializing integers 
a = 1
b = 2 
# initializing tuple 
tup = (('a', 1) ,('f', 2), ('g', 3)) 
# printing integer converting to complex number 
c = complex(1,2) 
print ("After converting integer to complex number : ",c)  
# printing integer converting to string 
c = str(a) 
print ("After converting integer to string : ",c)   
# printing tuple converting to expression dictionary 
c = dict(tup) 
print ("After converting tuple to dictionary : ",c)  

After converting integer to complex number : (1+2j)

After converting integer to string : 1

After converting tuple to dictionary : {'a': 1, 'f': 2, 'g': 3}
