We can count the number of a word's ocurrence in a list using the Counterfunction.
我们可以使用该Counter函数计算一个单词在列表中出现的次数。
from collection import Counter
string = ["mahesh","hello","nepal","nikesh","mahesh","nikesh"]
count_each_word = Counter(string)
print(count_each_word)
Output:
输出：
Counter({mahesh:2},{hello:1},{nepal:1},{nikesh:2})
计数器({mahesh:2},{hello:1},{nepal:1},{nikesh:2})

This is another solution:
这是另一种解决方案：
You can clean your data first and then count the result, something like that:
您可以先清理数据，然后计算结果，如下所示：
mylist = ["Mahon Point retail park", "Finglas","Blackpool Mahon", "mahon point blanchardstown"]
for item in mylist:
for char in "-.,":
item = item.replace(char, '')
item_word_list = item.split()
print(len(item_word_list))
The result:
结果：
4
1

mylist = ["Mahon Point retail park", "Finglas","Blackpool Mahon", "mahon point blanchardstown"]
flage = True
for string1 in mylist:
n = 0
for s in range(len(string1)):
if string1[s] == ' ' and flage == False:
n+=1
if string1[s] == ' ':
flage = True
else:
flage = False
print(n+1)
