【问题描述】：
我的RDD如下：

我想检查最后一个元素（令牌）是否是连字符，如果是，则将其替换为零。我的代码如下：
def process_row(row):
words = row.replace('"', '').split(' ')
words.map(lambda row: 0 if x[5] == '-' else x[5])
return words
nasa = (
nasa_raw.flatMap(process_row)
)
for row in nasa.take(5):
print(row)
当我尝试运行时出现错误object has no attribute map
我在这里缺少什么？
