python - ValueError : not enough values to unpack (expected 2, got 1) when splitting line

Question

with open("words_10percent.txt") as f:
   file_data = f.read()
word_frequency = {}
for line in file_data.split("\n"):
   word, frequency = line.split(",")
   word_frequency[word] = float(frequency)

在第5行中，尝试拆分行时出现值错误。

Answer 1

此代码是绝对正确的。没有错误。再次检查您的文本文件。

为了演示，我在'words_10percent.txt'文件中添加了以下四行:

Ram, 50.55
class, 45.88
black, 35.99
data, 35.60

我得到以下输出:

Ram
 50.55
class
 45.88
black 
 35.99
data
 35.60
