[英]Give inputs to a running program using Python
I am running a python script via terminal. 我正在通过终端运行python脚本。 The script contains a main function. 该脚本包含一个主要功能。 It runs other programs in some directory and all those programs are in Python too. 它在某个目录中运行其他程序,所有这些程序也都在Python中。
While running these sub programs, I need to enter their required input values in the terminal using this main program(not command line arguments). 在运行这些子程序时,我需要使用此主程序在终端中输入其所需的输入值(而不是命令行参数)。
Ex: 例如:
MainProgram calls --dir1/pg1.py MainProgram调用--dir1 / pg1.py
----inputs 10 20 30
Main program calls --dir1/pg2.py 主程序调用--dir1 / pg2.py
----inputs 100 20 30 like wise the inputs to the subprograms are to be given by the main program.
I am trying to automate the process of giving input to a program and I need to do it with the help of a program. 我正在尝试自动化向程序提供输入的过程,而我需要在程序的帮助下进行操作。 Ex: the given below is a simple program for finding factorial 例如:下面给出的是查找阶乘的简单程序
i=1
fact=1
num=input("Enter the num : ")
while i<=num:
fact*=i
i+=1
print fact
I need a program(say MainProgram.py) that on execution calls the above program and give the required input to it and gets the output and validates if it is right or not. 我需要一个程序(例如MainProgram.py),该程序在执行时会调用上述程序,并向其提供所需的输入,并获取输出并验证它是否正确。
Please help me with this. 请帮我解决一下这个。 Been searching for a solution for long. 一直在寻找解决方案。
Maybe you want the the input()
function. 也许您需要input()
函数。
vals = input("Enter values").split(" ")
print(vals)
The program will print the message "Enter values"
and wait for the user to enter something, then split each value into a separate list element and print the new list. 该程序将打印消息"Enter values"
并等待用户输入内容,然后将每个值拆分为单独的列表元素,然后打印新列表。
Assuming you enter 10 20 30
the vals
variable will be ["10", "20", "30"]
. 假设您输入10 20 30
则vals
变量将为["10", "20", "30"]
。
p = Popen(["python",programURL], stdin=PIPE, stdout=PIPE)
out = p.communicate(input=f.read())[0]
Got something like this. 有这样的事情。 But this is not effective when user inputs values in a loop. 但这在用户循环输入值时无效。
I think you are looking for the stdin and stdout. 我认为您正在寻找stdin和stdout。
Check these two programs when one finish writing then another read it 当一个完成写入然后另一个读取它时,请检查这两个程序
sender.py sender.py
#!/usr/bin/python
import sys
for i in range(0,10):
sys.stdout.write('baby\n')
reciever.py 收货人
#!/usr/bin/python
import sys
data = sys.stdin.read()
print data
Command to execute : ./sender.py | 执行命令:./sender.py | ./reciever.py ./reciever.py
output by receiver.py: 通过receiver.py输出:
baby
baby
baby
baby
baby
baby
baby
baby
baby
baby
