Take care not to use a mutable object as the default value of a parameter.(注意不要使用可变对象作为参数的缺省值) A series of calls to the function will use the same object, sometimes with bizarre results as we will see in the discussion of debugging below. None 分类: Python自然语言处理...

A Python function is not required to have a return statement. Some functions do their work as a side effect, printing a result, modifying a file, or updating the contents of a parameter to the function (such functions are called "procedures" in some other programming languages). Consider the...
The greet_bob() function, however, expects a function as its argument. You can, for example, pass it the say_hello() or the be_awesome() function.To test your functions, you can run your code in interactive mode. You do this with the -i flag. For example, if your code is in a...
When using files, you set the file object as the argument to stdin, instead of using the input parameter: Python >>> import subprocess >>> from tempfile import TemporaryFile >>> with TemporaryFile() as f: ... ls_process = subprocess.run(["ls", "/usr/bin"], stdout=f) ... ...
Arbitrary arguments allow us to pass a varying number of values during a function call. We use an asterisk (*) before the parameter name to denote this kind of argument. For example, # program to find sum of multiple numbersdeffind_sum(*numbers):result =0fornuminnumbers: ...
