Question

我是编程的新手，我试图使用终端运行这个python程序并收到错误：File "abc1234.py", line 9 time.sleep(3) IndentationError: expected an indented block ^

import webbrowser
import time
time_total=3
time_count=0
print (" the current time is " +time.ctime())
while(time_count<time_total):
time.sleep(3)
webbrowser.open("https://www.youtube.com/results?search_query=raabta+song+deepika")
time_count= time_count+1

Answer 1

根据您的输入，不确定如何格式化它。但是你的代码应该是这样的：

import webbrowser
import time
time_total = 3
time_count = 0
print (" the current time is " + time.ctime())
while(time_count < time_total):
    time.sleep(3)
    webbrowser.open("https://www.youtube.com/results?search_query=raabta+song+deepika")
    time_count = time_count + 1

您必须缩进while块中的所有代码。您必须在第9行上没有正确缩进time.sleep(3)。解释器期望在 while循环的冒号后面至少有一条缩进行。

Answer 2

那是因为您在没有缩进的情况下编写嵌套代码以下是它在Python中的工作原理：

import webbrowser
import time
time_total=3
time_count=0
print (" the current time is " +time.ctime())
while(time_count<time_total):
    time.sleep(3)
    webbrowser.open("https://www.youtube.com/results?search_query=raabta+song+deepika")
    time_count= time_count+1

文件＆＃34; abc1234.py＆＃34;，第9行time.sleep（3）^ IndentationError：预期缩进块
