從python調用腳本后，如何從python代碼中選擇單詞並在腳本shell中打印？

Question

我有代碼python

import os
# put the words you want to match into a list
matching_words = ["apple", "pear", "car", "house"]

# get some text from the user 
user_string = input("Please enter some text:")

# loop over each word in matching_words and check if it is a substring of user_string
for word in matching_words:
    if word in user_string:
        print("\n{} is in the user string\n\n".format(word))
        os.system('/home/raed/Desktop/1.sh')

我在腳本中有這段代碼

#! /bin/bash
########################
if [ "$2" = "pear" ]; then
    echo " This is '$2'"
elif [ "$2" = "apple" ]; then
    echo " This is '$2'"
else
    echo " This is '$2'"
exit 0

因此，如果我從 python 代碼列表中選擇任何單詞，我需要腳本識別並打印它

我有這個錯誤如何解決？！

Please enter some text:apple

apple is in the user string


/home/raed/Desktop/1.sh: line 10: syntax error: unexpected end of file

Answer 1

您需要將您的單詞作為參數包含在您的 python 程序中。

以下是對您的程序進行了一些小修改的代碼片段。

import os
# put the words you want to match into a list
matching_words = ["apple", "pear", "car", "house"]

# get some text from the user 
user_string = input("Please enter some text:")

# loop over each word in matching_words and check if it is a substring of user_string
for word in matching_words:
    if word in user_string:
        com = '/home/craig/Python_Programs/Script/1.sh ' + word
        print("\n{} is in the user string\n\n".format(word))
        os.system(com)

此外，在您的 bash 腳本中，您需要檢查參數 #1 ($1) 來代替參數 #2 ($2)，如以下腳本調整中所述。

#! /bin/bash
########################
if [ "$1" = "pear" ]; then
    echo " This is '$1'"
elif [ "$1" = "apple" ]; then
    echo " This is '$1'"
else
    echo " This is '$1'"
exit 0

fi

以下是我的終端的輸出示例。

Una:~/Python_Programs/Script$ python3 Script.py 
Please enter some text:apple

apple is in the user string


 This is 'apple'
Una:~/Python_Programs/Script$ python3 Script.py 
Please enter some text:pear

pear is in the user string


 This is 'pear'

我相信這會給你帶來你想要的結果。

問候，

您忘記使用fi終止 bash 腳本中的if語句

#! /bin/bash ######################## 
if [ "$2" = "pear" ]; 
then 
   echo " This is '$2'" 
elif [ "$2" = "apple" ];
then 
  echo " This is '$2'" 
else 
  echo " This is '$2'" 
exit 0
fi

您必須將參數傳遞給這篇文章中建議的腳本： https ://stackoverflow.com/a/14892402/10968621
