该题如何用python编写脚本

Question

两个文件a，b，文件每行是两列的K V对，空格分隔。
两个文件的行数不一定相同。
a 里每个K对应的V都是正确的。
b里K对应的V如果和a里一样，就当成是正确，否则当成是错误的
写脚本，把b中错误的KV对找出来。如果b中的K，在a里没有出现。就忽略掉，这个怎么写呢

Answer 1

aDic = {}
with open(r'a.txt', 'r', encoding='utf-8') as fileObj:
    for line in fileObj:
        k,v = line.strip().split(" ")
        aDic[k]=v
print(aDic)
bDic = {}
with open(r'b.txt', 'r', encoding='utf-8') as fileObj:
    for line in fileObj:
        k,v = line.strip().split(" ")
        bDic[k]=v
print(bDic)
for k,v in bDic.items():
    if k in aDic:
        if v==aDic[k]:
            print(f"b中的{k}的值{v}是正确的")
        else:
            print(f"b中的{k}的值{v}是错误的")
            pass
    else:
        print(f"b中的{k}略掉")

如果只要找出b中错误的KV对

aDic = {}
with open(r'a.txt', 'r', encoding='utf-8') as fileObj:
    for line in fileObj:
        k,v = line.strip().split(" ")
        aDic[k]=v

bDic = {}
with open(r'b.txt', 'r', encoding='utf-8') as fileObj:
    for line in fileObj:
        k,v = line.strip().split(" ")
        bDic[k]=v

cDic = {}
for k,v in bDic.items():
    if k in aDic and v!=aDic[k]:
        cDic[k]=v
print(cDic)
