Raw_input() Python (艰难学习Python练习11)

Question

我正在做Zed Shaw的“以艰难的方式学习Python”第三版中的提问练习，我的代码如下：

print "How old are you?",

age = raw_input()

print "How tall are you?",

height = raw_input()

print "How much do you weigh?",

weight = raw_input()

print "So, you're %r old, %r tall and %r heavy." % (age, height, weight)

输出应如下所示：

How old are you? 38

How tall are you? 6'2"

How much do you weigh? 180lbs

So, you're '38' old, '6\'2"' tall and '180lbs' heavy.

但是，因为我使用的是Python 3，所以最初的输出如下所示：

How old are you?
Traceback (most recent call last):
  File "script.py", line 2, in <module>
    age = raw_input()
NameError: name 'raw_input' is not defined

然后，就像我用input()替换raw_input()一样：

How old are you?
Traceback (most recent call last):
  File "script.py", line 2, in <module>
    age = input()
EOFError: EOF when reading a line

Answer 1

看起来您拥有的代码是python 2代码。这是一个带有python 3语法的修订版。

Here是关于最后一行中的.format()调用的一些阅读。我认为.format方法更容易理解。

here是对Python3中的input()函数的一些解读

age = input("How old are you?")

height = input("How tall are you?")

weight = input("How much do you weigh?")

print("So, you're {} old, {} tall and {} heavy.".format(age, height, weight))

Answer 2

对于Python3，尝试将所有的"raw_input()“替换为简单的"input()”，它取代了"raw_input()“。
