Python 可以在同一行中使用多条语句,语句之间使用分号 ; (semicolon) 分隔,以下是一个简单的示例: >>> a=1; b=2; c=a+b;print(c)3 print 输出 print, input, int, eval 等函数都是python内置(built-in)的标准函数,使用时不需要导入任何库(不需要使用import导入库),可以直接使用。 print(*objects,sep...
Python 的标准库提供了一个 keyword 模块,可以输出当前版本的所有关键字: >>> import keyword >>> keyword.kwlist ['False', 'None', 'True', 'and', 'as', 'assert', 'break', 'class', 'continue', 'def', 'del', 'elif', 'else', 'except', 'finally', 'for', 'from', 'global', '...
解决方法:不要使用Python语言关键字作为变量名、函数名或类名等。在Python Shell窗口中,使用help(‘keywords’)指令可以查看Python语言的关键字列表。 (6)忘记在if/elif/else/while/for/def/class等语句末尾添加冒号(:) 报错信息: SyntaxError:invalidsyntax AI代码助手复制代码 解决方法:在if/elif/else/while/for/...

In Python theimport...fromsyntax is actually afrom...importsyntax. We meant to write this instead: >>>fromurllib.requestimporturlopen Fortunately, Python 3.12 fixes that Watch out for misspelled keywords, missing keywords, and re-arranged syntax. Also be sure not to use reserved words as vari...
Case Sensitivity: Python uses case-sensitive names, so function names with different cases (e.g., my_function, my_function, my_function) are treated differently. Avoid Using Reserved Keywords: Avoid using Python's reserved keywords (e.g., def, if, else, for, while, etc.). Descriptive and...
Misspelling Keywords Another very common syntax error among developers is the simple misspelling of a keyword. Keywords are reserved words used by the interpreter to add logic to the code. For example:for,while,range,break,continueare each examples of keywords in Python. ...
