![]() Since we have seen all the types of string formatting and compared them, we can choose the best and most efficient string formatting technique for us.Example-1: > ''. New techniques and ways were created to counter the lack of efficiency or ability to handle complex formatting. So far we conclude that all the ways performed for string formatting are different from each other, each of them has a unique style of formatting. Print(my_str.substitute(x= character, y= name, z=country)) For example, if during parsing a HTML document aheader is encountered, the formatter.My_str = Template("$x was created by $y for Marvel in $z.") import formatter Then what What is the purpose of this module There is no unit test for this module so I can not find any examples. In this technique of formatting, formatters work by putting the placeholders enclosed by pair of curly braces ".") I found a formatter module in Python 3.4 (Lib/formatter.py). Str.format() method is pretty simple and fast as compared to "%" operator formatting and is introduced in Python3. This method is suitable for handling complex string formatting more efficiently. This method is introduced to get rid of the % operator formatting. You can notice the difference in both the results. Here, the first print statement gets padded with whitespace. If the whole number doesn't have the specified number of digits then it might be padded with whitespace. Using multiple format conversion types in a single string.Įxample - 3: name = "Yashwant" print( "My %s %s bought the car worth $%d." %( 'friend', name, 15000))įloating-point Precision using the % operator print( "The length of land is: %2.3f metres" %( 85.52590))įloating-point numbers use an x.yf format, where x is a minimum number of digits in a string and yf represents how many digits have to display after the decimal point. We can insert multiple strings as well as we can use variables to insert objects in the string.Įxample - 2: x = "car" print( "The dog %s down the %s." %( 'chased', x)) Let's look at the examples showing different formatting conditions.Įxample - 1: Formatting the integer values print( "I bought %d apples and %d oranges." %( 6, 4)) These are the top rated real world Python examples of string.Formatter extracted from open source projects. We have some format specifiers that we use commonly: I used the "%s" format specifier to insert the string "Python" on that specific position. ![]() We use format specifiers to tell Python that you have to substitute the given value in that specific position. Name = "Python" print( "Hello, %s" %name) Here's an example: # An example to demonstrate the use of the operator for string formatting Modulo (%) operator is also known as "String-formatting" or "String-interpolation" operator. The same operator we use in the oldest style of string formatting. If you are aware of arithmetic operators in Python then you would know that we use this operator to get the remainder of the dividend. ![]() ![]() This way of formatting the strings, use the % (modulo) operator. We will see the fundamentals of the ways mentioned above. There are 4 ways to perform string formatting that are all different from each other: What is string formatting? Well, we can call it the process in which we inject things dynamically into the string and return the formatted version of that string. We gonna walk through all the 4 types of methods and learn the use cases so that you can learn the fundamentals of different string formatting techniques. In this tutorial, we gonna discuss the 4 types of string formatting techniques in Python.
