string formatting in python %i

‘%s’ is used to inject strings similarly ‘%d’ for integers, ‘%f’ for floating-point values, ‘%b’ for binary format. For all formats, conversion methods visit the official documentation.,Format() method was introduced with Python3 for handling complex string formatting more efficiently. Formatters work by putting in one or more replacement fields and placeholders defined by a pair of curly braces { } into a string and calling the str.format(). The value we wish to put into the placeholders and concatenate with the string passed as parameters into the format function. ,To create an f-string, prefix the string with the letter “ f ”. The string itself can be formatted in much the same way that you would with str.format(). F-strings provide a concise and convenient way to embed python expressions inside string literals for formatting.,In this article, we will discuss how to format string Python. String formatting is the process of infusing things in the string dynamically and presenting the string. There are four different ways to perform string formatting:-

Output:

Misha walked and looked around.

Variable as integer = 12
Variable as float = 12.000000

Output:

He said his age is 6

Variable as integer = 12
Variable as float = 12.000000

Python uses C-style string formatting to create new, formatted strings. The "%" operator is used to format a set of variables enclosed in a "tuple" (a fixed size list), together with a format string, which contains normal text together with "argument specifiers", special symbols like "%s" and "%d".,Any object which is not a string can be formatted using the %s operator as well. The string which returns from the "repr" method of that object is formatted as the string. For example:,Get started learning Python with DataCamp's free Intro to Python tutorial.

Let's say you have a variable called "name" with your user name in it, and you would then like to print(out a greeting to that user.)

# This prints out "Hello, John!"
name = "John"
print("Hello, %s!" % name)

To use two or more argument specifiers, use a tuple (parentheses):

# This prints out "John is 23 years old."
name = "John"
age = 23
print("%s is %d years old." % (name, age))

Any object which is not a string can be formatted using the %s operator as well. The string which returns from the "repr" method of that object is formatted as the string. For example:

# This prints out: A list: [1, 2, 3]
mylist = [1, 2, 3]
print("A list: %s" % mylist)

I have to convert a code from Python2.x to Python3 (mostly string format) I came across something like this:

Logger.info("random String %d and %i".format(value1, value2))

To use formatted string literals, begin a string with f or F before the opening quotation mark or triple quotation mark. Inside this string, you can write a Python expression between { and } characters that can refer to variables or literal values.,To use formatted string literals, begin a string with f or F before the opening quotation mark or triple quotation mark. Inside this string, you can write a Python expression between { and } characters that can refer to variables or literal values. >>> year = 2016 >>> event = 'Referendum' >>> f'Results of the {year} {event}' 'Results of the 2016 Referendum' ,Formatted string literals (also called f-strings for short) let you include the value of Python expressions inside a string by prefixing the string with f or F and writing expressions as {expression}.,The % operator (modulo) can also be used for string formatting. Given 'string' % values, instances of % in string are replaced with zero or more elements of values. This operation is commonly known as string interpolation. For example:

>>> year = 2016 >>>
   event = 'Referendum' >>>
   f 'Results of the {year} {event}'
'Results of the 2016 Referendum'

>>> yes_votes = 42_572_654 >>>
   no_votes = 43_132_495 >>>
   percentage = yes_votes / (yes_votes + no_votes) >>>
   '{:-9} YES votes  {:2.2%}'.format(yes_votes, percentage)
' 42572654 YES votes  49.67%'

>>> s = 'Hello, world.' >>>
   str(s)
'Hello, world.' >>>
repr(s)
"'Hello, world.'" >>>
str(1 / 7)
'0.14285714285714285' >>>
x = 10 * 3.25 >>>
   y = 200 * 200 >>>
   s = 'The value of x is ' + repr(x) + ', and y is ' + repr(y) + '...' >>>
   print(s)
The value of x is 32.5, and y is 40000... >>>
   # The repr() of a string adds string quotes and backslashes:
   ...hello = 'hello, world\n' >>>
   hellos = repr(hello) >>>
   print(hellos)
'hello, world\n' >>>
# The argument to repr() may be any Python object:
   ...repr((x, y, ('spam', 'eggs')))
"(32.5, 40000, ('spam', 'eggs'))"

>>>
import math
   >>>
   print(f 'The value of pi is approximately {math.pi:.3f}.')
The value of pi is approximately 3.142.

>>> table = {
      'Sjoerd': 4127,
      'Jack': 4098,
      'Dcab': 7678
   } >>>
   for name, phone in table.items():
   ...print(f '{name:10} ==> {phone:10d}')
   ...
   Sjoerd == > 4127
Jack == > 4098
Dcab == > 7678

>>> animals = 'eels' >>>
   print(f 'My hovercraft is full of {animals}.')
My hovercraft is full of eels. >>>
   print(f 'My hovercraft is full of {animals!r}.')
My hovercraft is full of 'eels'.
