![]() ![]() It is quite evident from the above examples that the format function completely frees you from hard-coding the type of data to print and lets you focus on the formatting. 'The site TechBeamers helped me learn Python basics in just 7 days.' > 'The site days.'.format('TechBeamers', 'Python', 7) It replaces the first occurrence of curly brackets with the value provided as a parameter to the format function.Ĭheck out the below example. The format function requires curly brackets as a replacement for % modifiers. Please note that its creators also ported it for Python 2.6, one of the most used versions of Python till date. It used a mini-language that provided ease of use and more options. It was one of the newest features which got introduced in Python 3 for simplifying string formatting. Also, most programmers don’t find as intuitive as the new features in Python. The primary problem with the C printf style formatting is that it limits the parameters to be passed. In Python, there is a built-in method that can change a string that is in uppercase to lowercase. When changing a string to lowercase, it only applies to the letters.

You should note here that you need to postfix ‘%’ with a type-specific char to indicate the type of data to print. Output_str = 'I am studying %s and using %s as the programming language.' % (subject, language) Python also adheres to this type of formatting and can format values of all its data types with the % sign.Ĭheck out the below example. It is a pretty old style and will remind you of the C programming language. ![]() If you like to perform some simple string formatting, then try using the ‘%’ operator. Let’s first dig into the percentage (%) sign and see what it does. Python String.Format() Or Percentage (%) for Formatting We will explore the key differences between the ‘%’ operator and the string.format() function in this post. However, Python also has an alternate way for string formatting via the format() function. modulus operator) acts as a format specifier and so does it in Python. For example, in ‘C’ language, the ‘%’ sign (a.k.a. Like the most programming languages, Python too provides a mechanism to format a string. In this quick tutorial, you’ll get to know which method to choose between format() function or percentage (%) to use for string formatting in Python. ![]()
