从python调用脚本后，如何从python代码中选择单词并在脚本shell中打印？

Question

我有代码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')

我在脚本中有这段代码

#! /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，如果我从 python 代码列表中选择任何单词，我需要脚本识别并打印它

我有这个错误如何解决？！

Please enter some text:apple

apple is in the user string


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

您需要将您的单词作为参数包含在您的 python 程序中。

以下是对您的程序进行了一些小修改的代码片段。

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 脚本中，您需要检查参数 #1 ($1) 来代替参数 #2 ($2)，如以下脚本调整中所述。

#! /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

以下是我的终端的输出示例。

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'

我相信这会给你带来你想要的结果。

问候，

您忘记使用fi终止 bash 脚本中的if语句

#! /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

您必须将参数传递给这篇文章中建议的脚本： https ://stackoverflow.com/a/14892402/10968621
