I'm trying to figure out whether this is a method or function call - 357mag - Jul-04-2019 I'm doing some simple string formatting examples in Python and I'm using the old style C method for an example in my program. I understand that when you type %s within your string that is simple a placeholder for where your data or argument is going to go. But what I don't understand is when you type the final % right before your arguments in parentheses, is that actually a method or a function call? When people were doing C language did they learn that as a call to a function? Here is my code: subject = "Engineering" language = "Python" print("I am studying %s and using %s as the programming language" % (subject, language)) RE: I'm trying to figure out whether this is a method or function call - snippsat - Jul-04-2019 Don't use this old method anymore. f-string is what you should use,was new in Python 3.6(2-year ago).subject = "Engineering" language = "Python" print(f"I am studying {subject} and using {language} as the programming language") 11 year ago in 2.6 foramt() was new.subject = "Engineering" language = "Python" print("I am studying {} and using {} as the programming language".format(subject, language)) Not only are f-string far more readable more concise,and less prone to error than other ways of formatting,but they are also faster!>>> name = 'f-string' >>> print(f"String formatting is called {name.upper():*^20}") String formatting is called ******F-STRING****** # f-strings can take any Python expressions inside the curly braces. >>> cost = 99.75999 >>> finance = 50000 >>> print(f'Toltal cost {cost + finance:.2f}') Toltal cost 50099.76 >>> for word in 'f-strings are cool'.split(): ... print(f'{word.upper():~^20}') ... ~~~~~F-STRINGS~~~~~~ ~~~~~~~~ARE~~~~~~~~~ ~~~~~~~~COOL~~~~~~~~ RE: I'm trying to figure out whether this is a method or function call - ichabod801 - Jul-04-2019 To answer the original question, it's neither. It's an operator. |
