我们如何检索不区分大小写的单词？
问题描述：
things=[("red",1),("red",2),("green",5),("green",10),("red",15)]
for key,value in groupby(things,lambda x:x[0]):
for thi in value:
if(b==key):
print("things present in:",thi[1])
答
只需将casefold添加到您的字符串。
things=[("red",1),("red",2),("green",5),("green",10),("red",15)]
for key,value in groupby(things,lambda x:x[0]):
for thi in value:
if b.casefold() == key.casefold():
print("things present in: ", thi[1])
请注意，从上面的代码，如果我尝试检索“红色”或“红色”它应该显示红色相同的输出......请尽早帮助我！ –
只需在b和键上添加.lower（）（或上面的），那么你就不必再关心这个案例了 –
