Question

我正在运行Ubuntu 14.04 LTS，我有一个Python脚本集合，其中：

第一个脚本获取键盘输入，对其执行修改，并将修改后的输出存储在文件
第二个脚本读取第一个脚本生成的输出并获取（附加）键盘输入，执行操作，并将一些结果存储在第二个文件中
等

为了具体起见，我们假设我有两个Python脚本 1_script.py 和 2_script.py ，其源代码如下（at这篇文章的结尾）。

我想知道如何在终端中运行单个命令，执行以下所有操作：

执行 1_script.py
提供＆＃39;你好＆＃39;当 1_script.py 要求键盘输入时
执行 2_script.py
提供＆＃39;！＆＃39;当 2_script.py 要求键盘输入时

我很感激您在这方面可能提出的任何建议。

1_script.py

"""
This script:
    1) prompts the user to enter a string
    2) performs modifications to the entered string
    3) stores the modified string into a file 
"""

# get user input
user_entry = raw_input('Enter a string: ')

# perform modifications to the input
modified_data = user_entry + '...'

# store the modified input into a file
f = open('output_from_1_script.txt', 'w')
f.write(modified_data)
f.close()

2_script.py

"""
Dependencies:
    1) before executing this script, the script 1_script.py
        has to have been successfully run

This script:
    1) reads the output generated by 1_script.py
    2) modifies the read data with a user-supplied input
    3) prints the modified data to the screen
"""

# reads the output generated by 1_script.py
f = open('output_from_1_script.txt', 'r')
pregenerated_data = f.readline()
f.close()

# modifies the read data with a user-supplied input
user_input = raw_input('Enter an input with which to modify the output generated by 1_script.py: ')
modified_data = pregenerated_data + user_input

print modified_data

Answer 1

创建一个可以存储所有文件的目录您可以使用模块系统或将每个功能包含在同一个文件中转到目录并执行下面定义的mainfile.py

1_script.py

"""
This script:
    1) prompts the user to enter a string
    2) performs modifications to the entered string
    3) stores the modified string into a file 
"""
def get_input():
    # get user input
    user_entry = raw_input('Enter a string: ')

    # perform modifications to the input
    modified_data = user_entry + '...'

    # store the modified input into a file
    f = open('output_from_1_script.txt', 'w')
    f.write(modified_data)
    f.close()

下一个脚本将进入下一个文件

2_script.py

"""
Dependencies:
    1) before executing this script, the script 1_script.py
        has to have been successfully run

This script:
    1) reads the output generated by 1_script.py
    2) modifies the read data with a user-supplied input
    3) prints the modified data to the screen
"""
def post_input():
    # reads the output generated by 1_script.py
    f = open('output_from_1_script.txt', 'r')
    pregenerated_data = f.readline()
    f.close()

    # modifies the read data with a user-supplied input
    user_input = raw_input('Enter an input with which to modify the output     generated by 1_script.py: ')
    modified_data = pregenerated_data + user_input

    print modified_data

第三个脚本 mainfile.py

from 1_script import get_input
from 2_script import post_input

if __name__=='__main__':
    get_input()
    post_input()
    print "success"
