關(guān)于python使用字典的問題

如圖片，期末實(shí)訓(xùn)考核內(nèi)容，我已經(jīng)弄了三天了，后天就要交了，求幫幫忙，小弟再次感激不盡，另附上我寫的代碼

任務(wù)一

def one(path):

for i in open(path):
    list1=i.split()
    tuple1=tuple(list1)
    print(tuple1)

任務(wù)二

def tow(path):

open_tmp=open(path)
key_tmp=open_tmp.readline()
key1=key_tmp.split()
for i2 in open_tmp:
    key2=i2.split()
    zip_put=dict(zip(key1,key2))  
    print(zip_put)
