python3_判断A包含于B者A是B的子集

1、set1.issubset(set2)  #判断列表set1是set2的子集

str1="A01"                # 假设前端传这个字符串
str2="A01,A02,A03"        # 提前约定好的算法编码
set1=set(str1.split(","))
set2=set(str2.split(","))

print(str1.split(","))   #['A01']
print(str2.split(","))   #['A01', 'A02', 'A03']
print(set1)              #{'A01'}
print(set2)              #{'A02', 'A01', 'A03'}

if set1.issubset(set2):
    print(">>>set1是set2的子集") #>>>set1是set2的子集
