python123 的习题

Question

txt = open("命运.txt", "r", encoding="utf-8").read() #正式考试可以不用指定编码，用系统默认。
for ch in "↲":
    txt = txt.replace(ch, "")
d = {}
for ch in txt:
    d[ch] = d.get(ch, 0) + 1#将信息转换成字典
d_order=sorted(d.items(),key=lambda x:x[1],reverse=True)

for i in d_order[:11]:
    print(str(i[0]),end="")

这是我的代码，

txt = open("命运.txt", "r", encoding="utf-8").read()
for ch in '\n':
    txt = txt.replace(ch, "")
d = {}
for ch in txt:
    d[ch] = d.get(ch, 0) + 1
ls = list(d.items())
ls.sort(key=lambda x: x[1], reverse=True)  # 此行可以按照词频由高到低排序
for i in range(10):
    print(str(ls[i])[2], end="")

这是参考答案

结果十分魔幻
请问为什么会这样？

Answer 1

txt = open("命运.txt", "r", encoding="utf-8").read()
for ch in '\n':
    txt = txt.replace(ch, "")

# 这里print检查一下， 看看是否已经替换回车符了
print(txt)
