sys.stdin是一个类似于文件的对象,我们可以在其上调用函数read()或readlines() Example: 例: from sys import stdin input = stdin.read(1) user_input = stdin.readline() amount = int(user_input) print("input = {}".format(input)) print("user_input = {}".format(user_input)) print("amount ...

This tutorial discusses methods to read input from stdin in Python. This can be either reading from the console directly or reading from the filename specified in the console. Use fileinput.input() to Read From stdin in Python We can use the fileinput module to read from stdin in Python....
In the previous parts of theAwk tool series, we looked at reading input mostly from a file(s), but what if you want to read input fromSTDIN. In this Part 7 of Awk series, we shall look at few examples where you can filter the output of other commands instead of reading input from ...
But in the second version of code I am bound to read fixed number of arguments fromstdin. How can I read arbitrary number of arguments fromstdin? You can loop over condition and keep on reading input from stdin until that condition is satisfied. In below example if input is "exit" progra...
Thus, here's how you can use input in Python 3 (or raw_input in Python 2) to read from stdin - so we create a Python module we call stdindemo.py: $ python -c "print('try:\n while True:\n print(input())\nexcept EOFError:\n pass')" > stdindemo.py And let's print it...
打印的input_line变量值可以看到这一点。 使用-p 选项指定提示字符串 执行read命令时,默认不打印提示字符串。 如果想要引导用户输入特定的内容,可以使用-p选项来指定提示字符串。 查看help read 对该选项的说明如下: -p prompt output the string PROMPT without a trailing newline before attempting to read ...
read命令是用于从终端或者文件中读取输入的内部命令,read命令读取整行输入,每行末尾的换行符不被读入。在read命令后面,如果没有指定变量名,读取的数据将被自动赋值给特定的变量REPLY。下面的列表给出了read命令的常用方式: 代码语言:javascript 复制 read 1987name ...
