如何在打印结束时添加句点

Question

基本的东西，我收到了一个语法错误。如何在打印行的末尾添加句点？

first_name = raw_input("Enter your first name: ")
last_name = raw_input("Enter your last name: ")
print "Enter your date of birth" 
month= raw_input("Month? ")
day= raw_input("Day? ")
year= raw_input("Year? ")

print "Here's your information"
print first_name, "was born on", month, day+',', year.

Answer 1

你需要连接它：

print first_name, "was born on", month, day+',', year, "."

更新：正如@ sr2222指出的那样，这将在句号之前打印一个额外的空格。如果你想避免它（并假设年份是一个字符串）：

print first_name, "was born on", month, day+',', year + "."

Answer 2

在它周围加上引号。

print first_name, "was born on", month, day+',', year +'.'

尽管如此，你应该清理它，因为在一行中组合一堆不同的字符串连接机制变得难以阅读。

print first_name + " was born on " + month + ", " + day + ", " + year + "."

当然还有the big wide world of string formatting。
