python - 如何在python中一个一个地遍历两个列表中的项目

Question

我试图遍历包含两个不同用户的两个列表，当两个列表中都有项目时 for 循环有效，但当其中一个列表没有任何项目时它不会工作。

customer_list = [["ctm1","Jackson","abc"],["ctm2","Kaijun","edf"]]
  admin_list  = [["adm1","Jackson","martinez"],["adm2","Littsen","Lit"]]

for customer,admin in zip(customer_list, admin_list):
     print(customer,admin)

admin_list 中没有项目

customer_list = [["ctm1","Jackson","abc"],["ctm2","Kaijun","edf"]]
admin_list = []

for customer,admin in zip(customer_list, admin_list):
     print(customer,admin)

a=[]

if a:
  

放在你的列表之后但在你的之前
