（Python）格式化列表中的元素

Question

所以我试图让我的列表中的元素长达7个字节但我没有运气试图自己做。

redChannelData = [46, 49, 50, 51, 53, 53, 54, 56, 59, 59, 60, 61, 62, 62, 64, 64, 65, 65]
redChannelList = []
for value in redChannelData:
    redChannelListBinary = bin(value)[2:]
    redChannelList.append(redChannelListBinary)
redChannelListBinaryList = [[int(b) for b in binary] for binary in redChannelList]
print(redChannelListBinaryList)

Output:

[[1, 0, 1, 1, 1, 0], [1, 1, 0, 0, 0, 1], [1, 1, 0, 0, 1, 0], [1, 1, 0, 0, 1, 1], [1, 1, 0, 1, 0, 1], [1, 1, 0, 1, 0, 1], [1, 1, 0, 1, 1, 0], [1, 1, 1, 0, 0, 0], [1, 1, 1, 0, 1, 1], [1, 1, 1, 0, 1, 1], [1, 1, 1, 1, 0, 0], [1, 1, 1, 1, 0, 1], [1, 1, 1, 1, 1, 0], [1, 1, 1, 1, 1, 0], [1, 0, 0, 0, 0, 0, 0], [1, 0, 0, 0, 0, 0, 0], [1, 0, 0, 0, 0, 0, 1], [1, 0, 0, 0, 0, 0, 1]]

Answer 1

我使用format函数并指定我最感兴趣的是7位。

redChannelData = [46, 49, 50, 51, 53, 53, 54, 56, 59, 59, 60, 61, 62, 62, 64, 64, 65, 65]
redChannelList = []
for value in redChannelData:
    redChannelListBinary = format(value, '07b')
    redChannelList.append(redChannelListBinary)
redChannelListBinaryList = [[int(b) for b in binary] for binary in redChannelList]
print(redChannelListBinaryList)

给出输出

[[0, 1, 0, 1, 1, 1, 0], [0, 1, 1, 0, 0, 0, 1], [0, 1, 1, 0, 0, 1, 0], [0, 1, 1, 0, 0, 1, 1], [0, 1, 1, 0, 1, 0, 1], [0, 1, 1, 0, 1, 0, 1], [0, 1, 1, 0, 1, 1, 0], [0, 1, 1, 1, 0, 0, 0], [0, 1, 1, 1, 0, 1, 1], [0, 1, 1, 1, 0, 1, 1], [0, 1, 1, 1, 1, 0, 0], [0, 1, 1, 1, 1, 0, 1], [0, 1, 1, 1, 1, 1, 0], [0, 1, 1, 1, 1, 1, 0], [1, 0, 0, 0, 0, 0, 0], [1, 0, 0, 0, 0, 0, 0], [1, 0, 0, 0, 0, 0, 1], [1, 0, 0, 0, 0, 0, 1]]

Answer 2

你可以尝试这样：

redChannelData = [46, 49, 50, 51, 53, 53, 54, 56, 59, 59, 60, 61, 62, 62, 64, 64, 65, 65]
redChannelList = []
for value in redChannelData:
    redChannelListBinary = bin(value)[2:]
    while len(redChannelListBinary) < 7:
        redChannelListBinary = '0' + redChannelListBinary
    redChannelList.append(redChannelListBinary)
redChannelListBinaryList = [[int(b) for b in binary] for binary in redChannelList]
print(redChannelListBinaryList)

输出：

[[0, 1, 0, 1, 1, 1, 0], [0, 1, 1, 0, 0, 0, 1], [0, 1, 1, 0, 0, 1, 0], [0, 1, 1, 0, 0, 1, 1], [0, 1, 1, 0, 1, 0, 1], [0, 1, 1, 0, 1, 0, 1], [0, 1, 1, 0, 1, 1, 0], [0, 1, 1, 1, 0, 0, 0], [0, 1, 1, 1, 0, 1, 1], [0, 1, 1, 1, 0, 1, 1], [0, 1, 1, 1, 1, 0, 0], [0, 1, 1, 1, 1, 0, 1], [0, 1, 1, 1, 1, 1, 0], [0, 1, 1, 1, 1, 1, 0], [1, 0, 0, 0, 0, 0, 0], [1, 0, 0, 0, 0, 0, 0], [1, 0, 0, 0, 0, 0, 1], [1, 0, 0, 0, 0, 0, 1]]
