Python连接未按预期工作

Python2代码:

healthamzn = "E:\ACADEMICS\PEC---\ME 4 SEM\code\data\amazon5core\healthcare"
jester = "E:\ACADEMICS\PEC---\ME 4 SEM\code\data\jester"

print(os.path.join(healthamzn, "healthcare5core.csv"))
print(os.path.join(jester,"jester_ratings.dat"))

输出:

E:\ACADEMICS\PEC---\ME 4 SEM\code\datamazon5core\healthcare\healthcare5core.csv E:\ACADEMICS\PEC---\ME 4 SEM\code\data\jester\jester_ratings.dat

请注意第一个输出不是我所期望的。

预期产量:

E:\ACADEMICS\PEC---\ME 4 SEM\code\data\amazon5core\healthcare\healthcare5core.csv
