Although this method is still a valid way to format strings, it can lead to errors and decreased clarity in code when you're dealing with multiple variables. Either of the other two formatting options described in this unit would be better suited to this purpose.The...
Supports the format mini-language✅✅⛔️ Supports conversion types✅✅✅ Supports conversion flags✅✅✅ F-strings are the clear winner in terms of readability. However, they don’t allow you to do lazy interpolation. There’s no way to use an f-string to create a reusable...

That is fine—we can include multiple%sas placeholders in the string and provide the variables in a parentheses after the%sign. This is illustrated the following code: icecream_selection=['strawberry','vanilla','chocolate']jelly_selection=['lime','orange','strawberry','raspberry','blackcurrant'...
当我们在英语中描述这些代码时,我们通常会说:“In Python, you can break a statement into multiple lines with a backslash or parentheses. In C++, you can break a statement into multiple lines with parentheses."(在Python中,你可以使用反斜杠或括号将语句分成多行。在C++中,你可以使用括号将语句分成多...
