Python，减少字符串列表不适用于换行符？

Question

我尝试使用 reduce 函数将字符串列表组合到字符串，但它不起作用。无论如何，我更喜欢使用 reduce 函数，我该如何解决这个问题？

>> reduce(lambda x, y: x + y + "\n", ["dog", "cat"])
# this doesn't work
# dogcat
>> "\n".join(["dog", "cat"])
# this works
# dog
# cat

Answer 1

join的目的，就是把元素放在每一个之间

reduce(lambda x, y: x + "
" + y, ["dog", "cat"])

Answer 2

###################### METHOD 1 ######################

strings = ["This", "is", "a", "list", "of", "strings"]

# join the strings using lambda
joined = lambda strings: "
".join(strings)
print(joined(strings))

###################### METHOD 2 ######################

mylist = ["a", "b", "c", "d", "e"]

# use list comprehension to join the list of strings
mystring = "
".join([str(x) for x in mylist])
print(mystring)

strings = ["This", "is", "a", "list", "of", "strings"]

###################### METHOD 3 ######################
import functools
list_of_strings = ["a", "b", "c"]
print(functools.reduce(lambda x, y: x + "
" + y, list_of_strings))
