为了解决EOF问题,我们可以使用try-except语句来捕获EOF错误,并在捕获到错误时进行处理。具体的方案如下: try:whileTrue:# 获取用户输入user_input=input("请输入:")# 处理用户输入process_input(user_input)exceptEOFError:# 用户输入结束,做一些清理工作cleanup()print("用户输入结束") 1. 2. 3. 4. 5. 6. ...
defget_user_input(prompt="请输入一些文本:"):whileTrue:try:user_input=input(prompt)returnuser_inputexceptEOFError:print("发生了EOFError:输入结束,没有数据可读取,请重新输入。")continueuser_input=get_user_input()print(f"你输入的文本是:{user_input}") 1. 2. 3. 4. 5. 6. 7. 8. 9. 10...

If the size argument is negative or omitted, read until EOF is reached. Notice that when in non-blocking mode, less data than what was requested may be returned, even if no size parameter was given. In [82]: f1.read(10) #返回最多10个字节的字符串 Out[82]: 'root:x:0:0' In [...
INTERPRETER INTERFACE The interpreter interface resembles that of the UNIX shell: when called with standard input connected to a tty device, it prompts for commands and executes them until an EOF is read; when called with a file name argument or with a file as standard input, it reads and ...

Input<str> = input() Reads a line from the user input or pipe if present (trailing newline gets stripped). If argument is passed, it gets printed to the standard output before input is read. EOFError is raised if user hits EOF (ctrl-d/ctrl-z⏎) or input stream gets exhausted....
