Question

我有这个清单

[['obytay'], ['ikeslay'], ['ishay'], ['artway']]

我需要它看起来像

obytay ikeslay ishay artway

有人可以帮忙吗？我尝试使用join，但我无法让它工作。

Answer 1

列表中有一个列表，因此它的工作方式与您认为的不同。然而，你的尝试是完全正确的。这样做：

' '.join(word[0] for word in word_list)

其中word_list是您上面显示的列表。

>>> word_list = [['obytay'], ['ikeslay'], ['ishay'], ['artway']]
>>> print ' '.join(word[0] for word in word_list)
obytay ikeslay ishay artway

这是一个字符串列表。因此，您需要使用chain.from_iterable这样的

链接字符串列表

from itertools import chain
print " ".join(chain.from_iterable(strings))
# obytay ikeslay ishay artway

如果我们首先将链式迭代转换为列表（如此

）将会很有效

print " ".join(list(chain.from_iterable(strings)))

def pig_latin(text):
  say = ""
  x=[]

  # Separate the text into words
  words = text.split()

  for word in words:
    # Create the pig latin word and add it to the list
    x.append(word[1:]+word[0]+'ay')

  for eachword in x:
    say += eachword+' '
    # Turn the list back into a phrase
  return say
        
print(pig_latin("hello how are you")) # Should be "ellohay owhay reaay ouyay"

print(pig_latin("programming in python is fun")) # Should be "rogrammingpay niay ythonpay siay unfay"

您也可以使用reduce。

l = [['obytay'], ['ikeslay'], ['ishay'], ['artway']]
print " ".join(reduce(lambda a, b: a + b, l))
#'obytay ikeslay ishay artway'
