print() 输出结果中显示引号

Question

当下面这段代码被激活时，它会在结果中显示所有的逗号、单引号（还有括号）。

print(name, 'has been alive for', days, 'days', minutes, 'minutes and', seconds, 'seconds!')

举个例子：

('Ryan', 'has been alive for', 10220, 'days', 14726544, 'minutes and', 883593928, seconds!')

我想把它整理得更好看一点，这可能吗？

我说的“好看”，是指像这样：

Ryan has been alive for 10220 days, 14726544 minutes, and 883593928 seconds!

这是完整的代码：

print("Let's see how long you have lived in days, minutes, and seconds!")
name = raw_input("name: ")

print("now enter your age")
age = int(input("age: "))

days = age * 365
minutes = age * 525948
seconds = age * 31556926

print(name, 'has been alive for', days, 'days', minutes, 'minutes and', seconds, 'seconds!')

raw_input("Hit 'Enter' to exit!: ")

Answer 1

你需要在代码开头加上 from __future__ import print_function。

在 Python 2.x 版本中，你的代码会被解释为打印一个元组，而你使用的是 3.x 版本的语法。

举个例子：

>>> name = 'Ryan'
>>> days = 3
>>> print(name, 'has been alive for', days, 'days.')
('Ryan', 'has been alive for', 3, 'days.')
>>> from __future__ import print_function
>>> print(name, 'has been alive for', days, 'days.', sep=', ')
Ryan, has been alive for, 3, days.
