为什么元组拆包会显示‘not enough arguments for format string’？

Question

最近在学习Python，元组拆包时显示‘not enough arguments for format string’，代码如下：
travler_ids = [('USA', '31195855'), ('BRA''CE342567'), ('ESP', 'XDA205856')]

for passport in travler_ids:
print('%s/%s' %passport)

控制台：
C:\thanatos\py366\python.exe E:/python1/流畅的python/元组和记录.py
USA/31195855
Traceback (most recent call last):
File "E:/python1/流畅的python/元组和记录.py", line 5, in
print('%s/%s' %passport)
TypeError: not enough arguments for format string

进程已结束，退出代码 1
