在python中搜索“開頭為”的標題？

Question

所以我有一個名字清單

name_list = ["John Smith", "John Wrinkle", "John Wayne", "David John", "David Wrinkle", "David Wayne"]

我希望能夠進行搜索，例如John和

John Smith
John Wrinkle
John Wayne

將顯示。 目前，我的代碼將顯示

John Smith
John Wrinkle
John Wayne
David John

我究竟做錯了什么？

這是我的代碼

search = input(str("Search: "))
search = search.lower()
matches = [name for name in name_list if search in name]
for i in matches:
    if(search == ""):
        print("Empty search field")
        break
    else:
        i = i.title()
        print(i)

Answer 1

將您的matches更改為：

matches = [name for name in name_list if name.startswith(search)]

您還可以對代碼進行一些更改：

# You can do this in one go
search = input(str("Search: ")).lower()

# Why bother looping if search string wasn't provided.
if not search:
    print("Empty search field")
else:
             # This can be a generator
    for i in (name for name in name_list if name.startswith(search)):
        print(i.title())
