删除Python打印行中的字符

Question

我正在编写一个程序，我希望光标在同一行上打印字母，然后删除它们，好像一个人正在打字，犯了错误，删回了错误，并继续打字那里。

到目前为止，我所有人都能够在同一条线上写下它们：

import sys, time
write = sys.stdout.write

for c in text:  
    write(c)
    time.sleep(.5)

Answer 1

write('\b')  # <-- backup 1-character

Answer 2

只是为了说明@ user590028和@Kimvais

给出的重要答案

sys.stdout.write('\b') # move back the cursor
sys.stdout.write(' ')  # write an empty space to override the
                       # previous written character.
sys.stdout.write('\b') # move back the cursor again.

# Combining all 3 in one shot: 
sys.stdout.write('\b \b')

# In case you want to move cursor one line up. See [1] for more reference.
sys.stdout.write("\033[F")

Answer 3

使用print（）时，可以将end设置为\ r，它将用新文本替换行中的文本。

print(text, end="\r")
