将文件转换为键/值字典

我不确定我是否正在创建一个新的字典。我想要一个文件，目前有两个单词用逗号分隔，每一行，并把它变成一个字典，第一个单词是关键字，第二个是值。我看到，如果我打印，这些单词是分开的，但我不确定是否正确返回。谢谢

I am unsure if what I have is actually creating a new dictionary. I want to take a file that currently has two words separated by commas on each line and turn it into a dictionary with the first word being the key and the second being the value. I see that if I print, the words are separated but I am unsure if it is returned correctly. Thanks

WDictionary = open('file.csv', 'r')
for line in WDictionary:
    mylist = line.split(',')
    return mylist
