在Python打印行中删除字符

Question

我正在编写一个程序，我希望光标在同一行上打印字母，但也要删除它们，就好像一个人正在输入，犯了一个错误，将其删除回到错误，并从那里继续打字。

所有我至今是他们写在同一行的能力：

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

只是为了说明通过@ user590028和@Kimvais

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")
