我在做 Learn Python the Hard Way(第 2 版,LPTHW)的第 16 次练习时遇到了一个奇怪的问题。
我首先输入了代码,复制了它,当我在控制台上执行脚本(使用 python ex16.py test.txt)时,会出现相同的消息:

File "ex16.py", line 19, in <module>  
line1 = input("line 1: ")  
TypeError: 'str' object is not callable    

代码是:

from sys import argv

script, filename = argv

print("We're going to erase %r." % filename)
print("If you don't want that, hit CTRL-C (^C).")
print("If you do want that, hit RETURN.")

input = ("?")

print("Opening the file...")
target = open(filename, 'w')

print("Truncating the file. Goodbye!")
target.truncate()

print("Now I'm going to ask you for three lines.")

line1 = input("line 1: ")
line2 = input("line 2: ")
line3 = input("line 3: ")

print("I'm going to write these to the file.")

target.write(line1)
target.write("\n")
target.write(line2)
target.write("\n")
target.write(line3)
target.write("\n")

print("And finally, we close it.")
target.close()  

这是因为 LPTHW 是为 Python 2.7 而我使用 Python 3.3 造成的吗?

input您在这里隐藏了内置函数:

input = ("?")

等号分配给一个名为 的变量input,它隐藏了内置input()函数。删除等号,您的代码将起作用:

input("?")

input = ("?")

注释掉上述内容并重试脚本。
