Python multiprocessing Pool can be used for parallel execution of a function across multiple input values, distributing the input data across processes (data parallelism). Below is a simple Python multiprocessing Pool example. Python多处理池可用于跨多个输入值并行执行功能,从而跨进程分配输入数据(数据并行...
解决方法:关键字/参数等号周围出现意外空格,去掉空格即可 PEP 8: multiple statements on one line (colon) 解决方法:多行语句写到一行了,比如:if x == 2: print('OK')要分成两行写 PEP 8: line too long (82 > 79 characters) 解决方法:超过了每行的最大长度限制79 PEP 8: Simplify chained compariso...

二、异常的高级用法 类似if-elif-else语句，try-except也可以多分支。此外，异常语句还可以与else和finally配合使用。如果try中没有异常，跳过except；如果没有，则执行except中的语句，跳过else。最后finally内的都会执行。Similar to if-elif-else statements, try-except can also be multiple branches. In addition...

If an exception occurs which does not match the exception named in theexcept clause, it is passed on to outertrystatements; if no handler is found, it is anunhandled exceptionand execution stops with an error message. Atrystatement may have more than oneexcept clause, to specify handlers for...
Python has simple and compound statements. A simple statement is a construct that occupies a single logical line, like an assignment statement. A compound statement is a construct that occupies multiple logical lines, such as a for loop or a conditional statement. An expression is a simple ...
A function that has one or more yield statements within it. Generator functions do not run when called; instead they return a generator object which will start running the function as it's being looped over. The Python documentation (confusingly in my opinion) sometimes refer to generator funct...
Here command may contain multiple statements separated by newlines. Leading whitespace is significant in Python statements! In non-interactive mode, the entire input is parsed before it is executed. If available, the script name and additional arguments thereafter are passed to the script in the Pyt...
