我一直在学习如何使用"Python绝对初学者指南"这本书编写Python程序.我遇到的问题是,使用eclipse-pydev它时不允许我使用该if语句.这是我写的代码......
name = input("What is your name? ")
print(name)
print("Hello" name )
结果是
What is your name? caleb
Traceback (most recent call last):
File "/Users/calebmatthias/Document/workspace/de.vogella.python.first/simpprogram.py", line 6, in <module>
name = input("What is your name? ")
File "/Users/calebmatthias/Desktop/eclipse 2/plugins/org.python.pydev_2.2.3.2011100616/PySrc/pydev_sitecustomize/sitecustomize.py", line 210, in input
return eval(raw_input(prompt))
File "<string>", line 1, in <module>
NameError: name 'caleb' is not defined
当我if发言时,我说
name = input("What is your name? ")
if name == ("Caleb"):
print(" Hello Bud!")
结果是
What …你好是使用eclipse和pydev,我想知道为什么我的示例代码不会尝试使用while函数.
print("Welcome to the annoying program")
response = ""
while response != "Because.":
response = input("why\n")
print("Oh,ok")
输出如下:
Welcome to the annoying program
why
Because.
Traceback (most recent call last):

return eval(raw_input(prompt))
File "<string>", line 1
Because.

SyntaxError: unexpected EOF while parsing
我在while循环中遇到了一些问题.我在eclipse上运行它,我输入了源代码:
a = raw_input("Mom im hungry!!!!!! FEED MEEEEE" )
while a != "Feed yourself":
print("Thats gross")
结果是当我输入错误的答案时,它会响应:
Thats gross
thats gross
等等.
