語法錯誤：在標識符

Question

嗨無效字符我剛開始用python.And而我想我的第一個程序我面臨這個問題：

python_mission = """ 
The mission of the Python Software Foundation is to promote, protect, 
and advance the Python programming language, and to support and 
facilitate the growth of a diverse and international community of 
Python programmer 
""" 
print(「The word returned is: {}」.format(python_mission[25:34])) 

Error: Invalid character in identifier

Answer 1

通知您在打印功能的報價是多麼的不一個普通的雙引號，但是是一個有角度的...當你的macOS的設置被設置爲它們的缺省值以使用它們時獲得的類型。

您需要的報價是定期的，所以......

print(「The word returned is: {}」.format(python_mission[25:34])) 

應該是...

print("The word returned is: {}".format(python_mission[25:34])) 

您也可以取消選中「使用智能引號和破折號」，以避免這種在未來：
