String Formatting in Python using %


In Python a string of required formatting can be achieved by different methods.
Some of them are ;
1) Using %
2) Using {}
3) Using Template Strings

In this article the formatting using % is discussed.

The formatting using % is similar to that of ‘printf’ in C programming language.
%d – integer
%f – float
%s – string
%x – hexadecimal
%o – octal

The below example describes the use of formatting using % in Python

# Python program to demonstrate the use of formatting using %
# Initialize variable as a string
variable = '15'
string = "Variable as string = %s" %(variable)
print string
# Printing as raw data
# Thanks to Himanshu Pant for this
print "Variable as raw data = %r" %(variable)
# Convert the variable to integer
# And perform check other formatting options
variable = int(variable) # Without this the below statement
                        # will give error.
string = "Variable as integer = %d" %(variable)
print string
print "Variable as float = %f" %(variable)

# printing as any string or char after a mark
# here i use mayank as a string
print "Variable as printing with special char = %cmayank" %(variable)

print "Variable as hexadecimal = %x" %(variable)
print "Variable as octal = %o" %(variable)

Output :

Variable as string = 15
Variable as raw data = '15'
Variable as integer = 15
Variable as float = 15.000000
Variable as printing with special char = mayank
Variable as hexadecimal = f
Variable as octal = 17
