如何使用Python从文件创建字典？

file = open('data.txt', 'r')

content = file.read()

file.close()

data = {}
lines = content.split('\n')
for line in lines:
    if line:
        key, value = line.split(',')
        data[key] = value

file = open('data.txt', 'r')
content = file.read()
file.close()

data = {}
lines = content.split('\n')
for line in lines:
    if line:
        key, value = line.split(',')
        data[key] = value

print(data)

key1,value1
key2,value2
key3,value3

{'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
