下面是一个可以实现flatten函数的Python代码: def flatten(lst): res = [] for i in lst: if isinstance(i, list): res.extend(flatten(i)) else: res.append(i) return res 这个函数首先创建了一个空列表res,然后遍历传入的列表lst中的所有元素。如果当前元素是一个列表,那么就递归地调用flatten函数,将返...
一. 默认方向是行方向,加’a'也是行方向,但是加‘f'是列方向 import numpy as np a = np.array([[1, 2], [3, 4], [5, 6], [7, 8]]) m = a.flatten() n = a.flatten('a') k = a.flatten('f') print(m) print(n) print(k) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11...
flatten在python中的用法 1. In Python, the `flatten` function is super useful! Let's say you have a list of lists, like `my_list = [[1, 2], [3, 4]].` Using `flatten`, you can turn it into a single list `[1, 2, 3, 4]`. It's like taking a bunch of little boxes (...
Flatten List of Lists Using Lambda An anonymous function can be defined using the lambda keyword. The regular/irregular list is passed as the argument to this anonymous function and the evaluation of the expression is done to obtain a flat 1D list: irregular_list = [[1,2,3], [3,6,7],...
