只是试图让一个元组添加到我的主要编程.无论如何这是我的代码 -
print"I have a few things to finish my exam, but i might need more"
exam=("Brain","Computer","python")
print "The stuff i have are:"
for stuff in exam:
print stuff
print"I still need my previous assignments!"
extra=("Assignments")
exam += extra
for stuff in exam:
print stuff
我一直得到的只能连接元组错误.任何人都有一个线索我的问题/如何解决它？非常感激.
