我正在尝试将一个类从一个文件导入到同一目录中的另一个文件,但是我似乎无法让python看到我编写的另一个文件。我正在尝试将我在random_walk.py文件中编写的RandomWalk类导入到rw_visual.py文件中。但是我得到了ImportError:尝试相对导入,没有已知的父程序包。任何帮助,将不胜感激。我从random_walk导入RandomWalk中获取错误
random_walk.py:
from random import choice
class RandomWalk:
def __init__(self, num_points=5000):
self.num_points = num_points
self.x_values = [0]
self.y_values = [0]
def fill_walk(self):
while len(self.x_values) < self.num_points:
x_direction = choice([1, -1])
x_distance = choice([0, 1, 2, 3, 4])
x_step = x_direction * x_distance
y_direction = choice([1, -1])
y_distance = choice([0, 1, 2, 3, 4])
y_step = y_direction * y_distance
if x_step == 0 and y_step == 0:
continue
# adds the _steps to the current position of the walk
x = self.x_values[-1] + x_step
y = self.y_values[-1] + y_step
self.x_values.append(x)
self.y_values.append(y)
rw_visual:
import matplotlib.pyplot as plt
from .random_walk import Randomwalk
rw = Randomwalk()
rw.fill_walk()
plt.style.use('classic')
fig, ax = plt.subplots()
ax.scatter(rw.x_values, rw.y_values, s=15)
plt.show()

在您的目录中添加空的__init__.py
