import sensor, image, time

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time = 2000)


while(True):
    img = sensor.snapshot()
    # one method   排序
    c = {3: 56, 5: 87, 2: 889, 1: 0}
    sorted(c.items(),key = lambda x:x[0], reverse = False)
    print("c: ", c)
    print("sor after: ", c)
    
    # two method   排序
    newDict = {}
    for i in sorted(c):
        newDict[i] = c[i]
        print("i: ", i, newDict[i])
    print("new: ", newDict)

按照key排序：

c = {3: 56, 5: 87, 2: 889, 1: 0}

for i in sorted (c) : 
    print(i,c[i])

结果

按照value排序

c = {3: 56, 5: 87, 2: 889, 1: 0}

print(sorted(c.items(),key = lambda x:x[1]))

结果

[(1, 0), (3, 56), (5, 87), (2, 889)]
