with open("earth_song.txt", "r") as f:
text = f.read()
text = text.lower()
for ch in '!@#$%^&*(_)-+=\\[]}{|;:\'\"`~,<.>?/':
text = text.replace(ch, " ")

words = text.split() # 以空格分割文本
stop_words = []
with open('stop_words.txt', 'r') as f: # 读取停用词文件
for line in f:
stop_words.append(line.strip('\n'))
afterwords = []

for i in range(len(words)):
z = 1
for j in range(len(stop_words)):

if words[i] == stop_words[j]:
continue
else:
if z == len(stop_words):
afterwords.append(words[i])
break
z = z + 1
continue
counts = {}
for word in afterwords:
counts[word] = counts.get(word, 0) + 1
items = list(counts.items())
items.sort(key=lambda x: x[1], reverse=True)

f1 = open('count.txt', 'w')
for i in range(len(items)):
word, count = items[i]
f1.write(word+" "+str(count)+"\n")
