python - time.sleep 有问题

Question

例如，当我运行时:

print("[",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("=",end=" ")
time.sleep(1)
print("]",end=" ")

10 秒内没有任何反应，然后整个 [ = = = = = = = = = = ] 出现。我怎样才能防止这种情况发生，以便它可以充当一种进度条？

尝试在每次打印后刷新标准输出:

import sys

print("=",end=" ")
sys.stdout.flush()
