遍历数据框时的未知值

Question

我正在使用性别猜测器库从名字中猜测性别。

import gender_guesser.detector as gender
 d = gender.Detector()

 print(d.get_gender(u"Bob"))
 male
gen = ['Alice', 'Bob', 'Kattie', "Jean", "Gabriel"]
female
male
female
male
male

但是当我尝试遍历pandas数据框时，我得到的输出为未知

for name in df1['first_name'].iteritems():
print(d.get_gender(name))

Answer 1

一种方法是使用地图。

   for line in file_read:
      try:       
          print(eval(line), file=file_write)
      except NameError:
          print("Bad Expression", file=file_write)

它将创建一个名为“性别”的新列。我认为应该比迭代更快。
