dataScientist.intersection(dataEngineer) # Equivalent Result dataScientist & dataEngineer 交集运算返回的集合可以被可视化为下面韦恩图中的红色部分。 你可能会发现,你会遇到你想确保两个集合没有共同值的情况。换句话说,你想得到两个交集为空的集合。这两个集合称为互斥集合,你可以使用「isdisjoint」方法测试两个...
经仔细观察,我们发现这两个项目具有不同的生命周期,那么使用约当年金(Equivalent Annual Annuity,EAA)的方法会更有效。 约当年金法是把生命周期为N年的现金流贴现到第1年年初,并用该现值等价成一个N年期的年金,从而得到的年金金额即为约当年金。 在Python中,使用numpy.pmt()函数计算约当年金。 numpy.pmt(rate,...
where the final value of s1 is equivalent either by: an assigned OR operation an in-place OR operation an in-place OR operation via special method 示例代码: s1 = {"a", "b", "c"} s2 = {"d", "e", "f"} s_or = s1 | s2 # OR, | print("s1: " + str(s1)) # s1 is ...
By default this is equivalent to float(num_str). This can be used to use another datatype or parser for JSON floats (e.g. decimal.Decimal). ``parse_int``, if specified, will be called with the string of every JSON int to be decoded. By default this is equivalent to int(num_str...
Themock.create_autospecmethod creates a functionally equivalent instance to the provided class. What this means, practically speaking, is that when the returned instance is interacted with, it will raise exceptions if used in illegal ways. More specifically, if a method is called with the wrong ...
Syntax is the equivalent in Python coding. A computer can’t understand the commands unless they're laid out properly. Syntax defines the proper way to lay out commands in Python.Throughout the Python content in Minecraft, there will be numerous opportunities for student...
Here’s the equivalent code in Python: Python code to output a message from the user. Python is also case-sensitive, so a variable with an incorrect case would also result in an error. Notice the error on line 8 where we useMessagewith a capital M instead ofmessage. ...

The closest Python equivalent to Electron (to my knowledge) iscefpython. It is a bit heavy weight for what I wanted. Eel is not as fully-fledged as Electron or cefpython - it is probably not suitable for making full blown applications like Atom - but it is very suitable for making the...
