python中的raw_input怎么用,如何在Python中的raw_input的行上打印？

Usually, when raw_input asks you to type something in and press Return, feedback is printed on a new line. How can I print over the prompt&＃39;s line? Could a CR work in this case?

Demo:

prompt &＃61; "Question: "

answer &＃61; raw_input(prompt)

print answer

print("Correct!")

Simulated output after typing an answer and pressing Return:

>> Question: my answer

>> Correct!

Desired output:

>> Correct!

解决方案from blessings import Terminal

term &＃61; Terminal()

raw_input("Question: ")

print(term.move_up() &＃43; "Correct!" &＃43; term.clear_eol())

Seriously, that&＃39;s it.

Here&＃39;s something fancier:

input(term.red("Question: ") &＃43; term.bold)

print(term.normal &＃43; term.move_up &＃43; term.green("Correct!") &＃43; term.clear_eol)

This shows that often calling term.thing is optional because they act similarly to properties. This means you can do awesome stuff like

from blessings import Terminal

term &＃61; Terminal()

question &＃61; "{t.red}{}{t.normal}{t.bold}".format

answer &＃61; "{t.normal}{t.move_up}{t.green}{}{t.normal}{t.clear_eol}".format

input(question("Question: ", t&＃61;term))

print(answer("Correct!", t&＃61;term))
