Question

我愿向一位现成的轴心提出关键词词。这是可能的吗?

ie something like

import matplotlib.pyplot as plt

kwargs = { xlim :(0, 2),  ylabel : y }

fig, ax = plt.subplots()
ax.give_kwargs(**kwargs)

页: 1 Axes 类别有**kwargs论据,但(一) 只有在物体初始化期间,而不是在物体已经存在之后,方可提供。

Edit:

避免X Y problem。这里是想做类似事情的背景。

What I find myself doing a lot is creating functions that plot some generalized data and I have to add 5+ extra arguments to handle all of the "set" methods for the axes:

def fancy_plot(data_arg1, dataarg2, xlim=None, ylabel=None):

    fig, ax = plt.subplots()
    ax.plot(data[data_arg1], data[data_arg2])

    if xlim: ax.set_xlim(xlim)
    if ylabel: ax.set_ylabel(ylabel)

Answer 1

是的,我们可以将<条码>kwargs dictionnary 和一套方法和论点。

import matplotlib.pyplot as plt

kwargs = { set_xlim : (0, 2),  set_ylabel :  y }

fig, ax = plt.subplots()
for (method, arguments) in kwargs.items():
    getattr(ax, method)(*arguments)

或者,如果所有方法都沿用<代码>_~thing。命名公约:

import matplotlib.pyplot as plt

kwargs = { xlim : (0, 2),  ylabel :  y }

fig, ax = plt.subplots()
for (method, arguments) in kwargs.items():
    getattr(ax, f"set_{method}")(*arguments)

You can then wrap the getattr part in a try-except in case your dictionnary contains names that are not existing ax methods.

for (method, arguments) in kwargs.items():
    try:
        getattr(ax, f"set_{method}")(*arguments)
    except AttributeError:
        print("Please everyone panic.")
