如何自動化的幾個相互依存的Python腳本

Question

執行我運行Ubuntu 14.04 LTS，我有Python腳本，其中集合：

• 第一個腳本獲取鍵盤輸入，進行修改，以使其，並存儲在一個文件中
• 的修改的輸出的第二腳本讀取由第一腳本和獲取（附加的）鍵盤輸入產生的輸出，在第二文件
• 等進行操作，並存儲一些結果

爲了具體說明，我們假設我有兩個Python腳本1_script.py和2_script.py，其源代碼在下面給出（在本文結尾處）。

我想知道我怎麼能在執行所有以下操作的終端中運行一個命令：

1. 執行1_script.py
2. 提供「你好」時1_script。 PY詢問鍵盤輸入
3. 執行2_script.py
4. 提供了 '！'當2_script.py詢問鍵盤輸入

我會很感激你可以在這方面提供任何的建議。

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

創建一個目錄，您可以存儲所有文件 您可以使用模塊系統或包括每個函數進同一文件 進入目錄並執行下面定義的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() 

下一個腳本會在接下來的文件

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 

第三個腳本 mainfile.py

from 1_script import get_input 
from 2_script import post_input 

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