[如何修复for循环中'for word in word'的语法错误-Python？ [处于保留状态]

Question

我是一个尝试创建字频计数器代码的初学者。我无法理解第3行中的语法错误以及如何解决此问题。

txt = "apple  mango apple mango"

words = txt.split()

for word in words
print (word + " " + str(txt.count())
import pandas
mytable = pd.DataFrame()

错误信息：

file "<ipython-input-6-8b828a5c935c>", line 3
      for word in words
                       <
SyntaxError: invalid syntax

Answer 1

您的代码中缺少冒号。应该是：

import pandas

txt = "apple  mango apple mango"

words = txt.split()

for word in words:
    print (word + " " + str(txt.count())
    mytable = pd.DataFrame()
