Python 的語法與其他編程語言

Python was designed for readability, and has some similarities to the English language with influence from mathematics. Python 是為可讀性設計的，與英語有一些相似之處，并受到數學的影響。

Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses. Python 使用新行來完成命令，而不像通常使用分號或括號的其他編程語言。

Python relies on indentation, using whitespace, to define scope; such as the scope of loops, functions and classes. Other programming languages often use curly-brackets for this purpose. Python 依賴縮進，使用空格來定義范圍；例如循環、函數和類的范圍。其他編程語言通常使用花括號來實現此目的。

Python Indentation Python 的縮進

Indentation refers to the spaces at the beginning of a code line.?縮進指的是代碼行開頭的空格。

Python uses indentation to indicate a block of code. Python 使用縮進來指示代碼塊。

Python will give you an error if you skip the indentation.?如果省略縮進，Python 會出錯。

The number of spaces is up to you as a programmer, but it has to be at least one.?空格數取決于程序員，但至少需要一個。

You have to use the same number of spaces in the same block of code, otherwise Python will give you an error.?您必須在同一代碼塊中使用相同數量的空格，否則 Python 會出錯。

縮進要點總結：

1. Python用縮進指示代碼塊。

2. 不可省略縮進。

3. 沒有規定空格數，但同一代碼塊中的空格格式要保持一致。
