我想显示第一个列表中的第一个单词,显示第二个列表中的10个单词,依此类推python

list2=[] ###-I am collecting all span tags ,storing as text in variable called alpha. for i in range(len(contents)): for j in contents[i].findAll('span'): alpha=j.text # print(alpha) alphachar=re.sub('[^a-zA-Z]+', '', alpha) #I am eliminating empty lists. alphabets=alphachar.split() #converting to list for item in alphabets: if item!=[]: list2.append(item) #I am appending to lists for (a, b) in zip(li,list2): print(a,b)

在这种情况下 range(len()) 有助于生成 i 对于 list2[i:i+10] .

使用

for i range(0, len(list2), 10):

您可以分配给 我 价值观 0 , 10 等,这将创造 list2[0:10] , list2[10:20] 等等。

list1 = ['Most actives', 'Gainers']

data = '''AMD AdvancedMicroDevicesInc

list2 = data.split('\n')

for name, i in zip(list1, range(0, len(list2), 10)):
    print('\n-', name, '\n')
    for item in list2[i:i+10]:
        print(item)

编辑: 我知道切片没有特殊功能 list2 但你可以创造自己的

(来源: How do you split a list into evenly sized chunks? )

def chunks(l, n):
    for i in range(0, len(l), n):
        yield l[i:i + n]

然后 for -循环 zip() 会看起来更好

def chunks(l, n):
    for i in range(0, len(l), n):
        yield l[i:i + n]


list1 = ['Most actives', 'Gainers']
