For example I have the list
like:
a = [143, 146, 152, 235, 246, 468, 476, 607, 615, 707, 712]
我想把它改成二维形式:
b = [
[143, 146, 152],
[235, 246],
[468, 476],
[607, 615],
[707, 712]
]
或:
"143 146 152
235 246
468 476
607 615
707 712"
但是从形状
list
的list
开始如何实现这个目标?
我有这样的东西:
devu = ''
for i in b:
for j in range(i):
devu += str(b[j])
devu += ' '
print(devu)
但结果是:
143146152 143146 143146 143146 143146
最佳答案
。使用iter
和一个简单的迭代。
演示:
a=[143, 146, 152, 235, 246, 468, 476, 607, 615, 707, 712]
a = iter(a)
shape =[3,2,2,2,2]
result = []
for s in shape:
temp = []
for i in range(s):
temp.append(next(a))
result.append(temp)
print(result)
Output:
[[143, 146, 152], [235, 246], [468, 476], [607, 615], [707, 712]]
