我是CSS的新手,只是构建了一个应用程序.问题是,在验证CSS时,我收到以下错误和警告:

有人可以解释这些错误和警告的含义以及如何修复它以便CSS可以被验证吗？

尽管存在这些错误,我的应用程序仍能正

这是我的CSS代码:

/*----------------------------CSS reset------------------------------*/

html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed, figure, figcaption, footer, header, hgroup, menu, nav, output, …

我想更新我的基本混乱游戏.我已经这样做了脚本从文本文件中获取单词,现在我想将它们分成模块,因为我有不同的文本文件.

我有我的主脚本jumble_game.py:

import random
import amazement

#Welcome the player
print("""
    Welcome to Word Jumble.
        Unscramble the letters to make a word.
""")

def wordlist(file):
    with open(file) as afile:
        global the_list
        the_list = [word.strip(",") for line in afile for word in line.split()]
    print(the_list)

def main():
    score = 0
    for i in range(4):
        word = random.choice(the_list)
        theWord = word
        jumble = ""
        while(len(word)>0):
            position = random.randrange(len(word))
            jumble+=word[position]
            word=word[:position]+word[position+1:]
        print("The jumble word is: {}".format(jumble))

        #Getting player's guess
        guess = input("Enter your guess: ").lower() …

我想用python做一个混乱的游戏，它使用文本文件中的单词，而不是直接写入python文件中的单词（在这种情况下，代码可以完美工作）。但是当我要导入它们时，我得到以下列表：

[['amazement', ' awe', ' bombshell', ' curiosity', ' incredulity', '\r\n'], ['godsend', ' marvel', ' portent', ' prodigy', ' revelation', '\r\n'], ['stupefaction', ' unforeseen', ' wonder', ' shock', ' rarity', '\r\n'], ['miracle', ' abruptness', ' astonishment\r\n']]

我希望单词在一个列表中排序，例如：

["amazement", "awe", "bombshell"...]

这是我的python代码：

import random

#Welcome the player
print("""
    Welcome to Word Jumble.
        Unscramble the letters to make a word.
""")


filename = "words/amazement_words.txt"

lst = []
with open(filename) as afile:
    for i in afile:
        i=i.split(",")
        lst.append(i)
print(lst)

word = random.choice(lst)
theWord …

我有一个数据集，这是一个例子：

df = DataFrame({"Seconds_left":[5,10,15,25,30,35,5,10,15,30], "Team":["ATL","ATL","ATL","ATL","ATL","ATL","SAS","SAS","SAS","SAS"], "Fouls": [1,2,3,3,4,5,5,4,1,1]})


   Fouls  Seconds_left Team
0      1             5  ATL
1      2            10  ATL
2      3            15  ATL
3      3            25  ATL
4      4            30  ATL
5      5            35  ATL
6      5             5  SAS
7      4            10  SAS
8      1            15  SAS
9      1            30  SAS

现在我想插入在 Seconds_left 列中缺少数据的行：

Id Fouls Seconds_left   Team
0      1            5    ATL
1      2           10    ATL
2      3           15    ATL
3    NaN           20    ATL
4      3           25    ATL
5      4           30 …

我有Heroku的问题.以下是日志文件:
