python 字典写到文件夹 python将字典保存在文件中

python 将字典dict保存到csv文件中

方法一

saveDict={"用户1":"密码1"，"用户2":"密码2"}
fileName="filename.csv"
##保存文件
with open(fileName,"wb") as csv_file:
	writer=csv.writer(csv_file)
	for key,value in saveDict.items:
		writer.writerow([key,value])

##读取文件
readDict={}
with open(fileName,"rb") as csv_file:
	reader=csv.reader(csv_file):
	readDict=dict(reader)

方法二

with open('my_file.csv', 'w') as f:
    [f.write('{0},{1}\n'.format(key, value)) for key, value in my_dict.items()]
