import datetime
time_tuple = (2019, 5, 6, 13, 8, 10)
print(datetime.datetime(time_tuple))

报错：

TypeError: an integer is required (got type tuple)

但是 print(datetime.datetime(2019, 5, 6, 13, 8, 10))完全没问题

datetime

time_tuple

TypeError

datetime.datetime(year, month, day[, hour[, minute[, second[, microsecond[, tzinfo]]]]])
看 api 文档

#2 #3 正解，你应该看一下不定参数的函数是怎么调用的

datetime.datetime() 第一个参数是 year

你给它一个元组，怎么能不报错

报错的给了一个参数，是 tuple
不报错的给了 6 个参数
