We can call the function by typing its name followed by parentheses (). Mode is an analytics platform that brings together a SQL editor, Python notebook, and data visualization builder. This is similar to Currying, which is the technique of translating the evaluation of a function that takes multiple arguments into evaluating a sequence of functions, each with a single argument. It uses English keywords frequently where as other languages use punctuation, and it has fewer syntactical constructions than other languages. If the block of an executable statement of if - clause contains only a single line, programmers can write it on the same line as a header statement. The file is always overwritten, though when it can, IPython asks for confirmation first. This is convenient, but can also lead to errors if there is no closing Parenthesis, bracket or brace. Python had been killed by the god Apollo at Delphi. Without the comma Python treats ('a') as an expression with a string in parentheses that evaluates to a string: >>> t2 = ('a') >>> type(t2) Another way to construct a tuple is the built-in function tuple. html](https://docs.
