Delete Characters in Python Printed Line

When you are using print(), you can set end as \r, which will replace the text in the line with the new text.

print(text, end="\r")

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

Just to illustrate the great answers given by @user590028 and @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")
