#python #pythontutorials #pythontutorialforbeginners #pythoncode #pythonprogramming #pythonclasses In Python, you can use various methods and formatting options to format numbers and strings. Here are some common techniques: 1. Formatting Numbers: format() method: Use the format() method to format numbers with specific precision, alignment, and padding. It uses placeholders {} that are replaced with the formatted values. number = 3.14159 formatted = "{:.2f}".format(number) # Two decimal places print(formatted) # Output: 3.14 f-strings (formatted string literals): Introduced in Python 3.6, f-strings provide a concise way to format strings, including numbers. number = 3.14159 formatted = f"{number:.2f}" # Two decimal places print(formatted) # Output: 3.14 2. Formatting Strings: % operator: Use the % operator to format strings, similar to C-style formatting. It uses format specifiers to define the desired formatting. name = "John" age = 25 formatted = "My name is %s and I'm %d years old." % (name, age) print(formatted) # Output: My name is John and I'm 25 years old. format() method: As mentioned earlier, you can also use the format() method to format strings by providing placeholders and replacement values. name = "John" age = 25 formatted = "My name is {} and I'm {} years old.".format(name, age) print(formatted) # Output: My name is John and I'm 25 years old. f-strings (formatted string literals): With f-strings, you can directly embed variables and expressions within the string. name = "John" age = 25 formatted = f"My name is {name} and I'm {age} years old." print(formatted) # Output: My name is John and I'm 25 years old. These are just a few examples of formatting numbers and strings in Python. The formatting options can be further customized to suit your specific requirements.
