使用python计算每个地址在数据文件中出现的次数

Answer 1

你可以用^{}:

from collections import Counter 

words = []

for line in open('data.txt'):
  # Your logic here
  words.append(line.split()[1])

words_dict = Counter(words)

for key, value in words_dict.items():
  print(key, value)

输出：

303574 1
55596 3
303630 1
303567 1
303595 1
303616 1
240840 3
303588 1
55590 1
303623 1
303602 1
303581 1
55608 3
303609 1
