Python第二次写的代码

#!/bin/bash/env python

#function:将大于66值保存在第一个字典键中，小于66保存在第二个

i1 = [11,22,33,44,55,66,77,88,99,90]
dict = {
    ‘k1‘: [],
    ‘k2‘: [],
}
for i in i1:
    if i <= 66:
        dict[‘k1‘].append(i)
    else:
        dict[‘k2‘].append(i)
print(dict)

结果：
{‘k1‘: [11, 22, 33, 44, 55, 66], ‘k2‘: [77, 88, 99, 90]}
