我建立一個三維陣列self.QL={} 和「擦除」的陣列0的: for loop0 in range(50):
for loop1 in range(50):
for loop2 in range(self.actions):
self.QL[loop0, loop1, loop2] = 0
但是當我運行該程序,並嘗試從陣列得到的值,它牛逼hrows的錯誤:
我試圖創建一個簡單的表單來添加用戶。我使用內置的表單生成UserCreationForm()。我找到了我使用的示例代碼here。 這裏是我的看法: def user_add(request):
if request.method == "POST":
form = UserCreationForm(request.POST)
if form.is_valid():
所以我每次嘗試提交表單時都會收到一個KeyError錯誤。 我在here之前問過類似的問題,該解決方案似乎工作了一段時間,但現在我得到了上面提到的KeyError。 代碼及以下的足跡: 形式: class CodingForm(forms.Form):
NATIONAL = 0
REGIONAL = 1
LOCAL = 2
NA = 99
SCOP
我有以下代碼: def search_for_person(name):
with open("address.txt", "r") as book:
records = re.split("[-]+", book.read(), re.M)
for data in records:
record = get_record(data)
代碼: import re
def add_details(details_dict, file_mode):
with open("address.txt", file_mode) as book:
book.write("Name: {}\n".format(details_dict['Name']))
book.write("Address: {}\n
我試圖從列表中添加邊: for first in G.nodes():
G_dict = copy.copy(G.node[first])
sorted_G = sorted(G_dict.iteritems(), key = op.itemgetter(1), reverse = True)
for number in range(0, close_limit):
