插入字符串变量时出现Python语法错误

Question

插入变量时出现简单错误。似乎无法解决这个问题！ meaning和word的类型为str。

rest_command = "display notification \'%s\' with title \'%s\'", %(meaning[0],word[0])
os.system(osascript -e + rest_command)

错误：

File "word-scraper.py", line 20
    rest_command = "display notification \'%s\' with title \'%s\'", %(meaning[0],word[0])
                                                                    ^
SyntaxError: invalid syntax

Answer 1

摆脱逗号

>>> "display notification \'%s\' with title \'%s\'" % (meaning[0],word[0])
"display notification 'hello' with title 'foo'"

或使用format

>>> "display notification \'{}\' with title \'{}\'".format(meaning[0],word[0])
"display notification 'hello' with title 'foo'"

Answer 2

您不需要字符串和＆＃39;％＆＃39;之间的逗号。
