Nested If Statements Nestedifstatements allow you to evaluate multiple conditions within a singleifblock. This is particularly useful when you need to check a series of conditions before executing a specific block of code. By nestingifstatements, you can create a more structured and efficient way ...
Python Nested if Statements It is possible to include anifstatement inside anotherifstatement. For example, number =5# outer if statementifnumber >=0:# inner if statementifnumber ==0:print('Number is 0')# inner else statementelse:print('Number is positive')# outer else statementelse:print(...

BLANK_LINE_BEFORE_NESTED_CLASS_OR_DEF 如果一个def或者class嵌套在另一个def或class中,那么就在前者之前插入一个空白行。 示例: BLANK_LINE_BEFORE_CLASS_DOCSTRING 在一个class-level docstring之前插入一行空白 COALESCE_BRACKETS 对连续括号不进行拆分,仅当设置了DEDENT_CLOSING_BRACKETS的时候才有用 示例: 重新格...
当if语句的条件部分足够长,需要跨多行编写时,值得注意的是,两个字符的关键字(即 if),加上一个空格,再加上一个开括号,会为多行条件的后续行创建一个自然的4个空格缩进。这可能会在if语句内嵌的缩进代码块的可视上产生冲突,后者也会自然地缩进到4个空格。这个PEP对如何(或是否)进一步在视觉上区分这样的条件行...
We have seen these conditionals in action throughout this chapter, but they have been used in simple if statements. Let's look at a more complex example. #!/usr/bin/python import os myuid = os.getuid() if myuid == 0: print "You are root" elif myuid < 500: print...

SyntaxError: multiple statements found while compiling a single statement 这是因为整体复制过去运行而产生的错误;解决方案如下: 方法一:先将第一行复制,敲一下回车,再将剩下的部分复制过去,运行; 方法二:Ctrl+N,新建一个,这时直接将代码复制进来,就不会产生这个问题了;直接在IDLE中编译,是每行都要回车的。如...
