Linux终端执行Python脚本与Id不同

Question

所以我写了一个程序，像旧的点阵打印机一样，一个字符一个字符地打印歌曲。当我在空闲状态下运行这个程序时，它可以运行并且工作正常，但是当我从Linux终端调用程序时，文本是逐行打印的，而不是逐字符打印的，这确实会影响程序的整体效果和要点。 我能做些什么来解决这个问题吗？或者是终端将如何使用它。谢谢

print ("<<<<<<<<<<<<<<<<<<<<<<< Portal Song Printer >>>>>>>>>>>>>>>>>>>>>>>")
ans = input("Still Alive(1) or Want You Gone(2):\n")
if ans == "1":
    song = """This was a triumph\nI'm making a note here: HUGE SUCCESS\nIt's hard
to overstate my satisfaction\n\nAperture Science\nWe do what we must because we can
For the good of all of us, except the ones who are dead\n\nBut there's no sense
crying over every mistake\nYou just keep on trying 'till you run out of cake
And the Science gets done\nAnd you make a neat gun\nFor the people who are still alive
\nI'm not even angry\nI'm being so sincere right now\nEven though you broke my
heart and killed me\n\nAnd tore me to pieces\nAnd threw every piece into a fire\nAs
they burned it hurt because I was so happy for you\n\nNow these points of data make
a beautiful line\nAnd we're out of beta, we're releasing on time\nSo I'm GLaD I got

for c in song:
    print(c, end="")
    time.sleep(.05)

Answer 1

终端按行缓存字符。你需要冲水：

import sys
for c in song:
    print(c, end="")
    sys.stdout.flush()
    time.sleep(.05)
