将2D数组中的每个数组转换为字符串

问题描述 投票:0回答:1

我试图将2D数组中的每个元素转换为字符串。所以例如我想把这样的[['a','b','c'],['x','y','z']]这样的东西转换成这样的东西['abc',' XYZ']。我很确定这是可能的,但我似乎无法理解如何。请告诉我一些事情。谢谢

我已经尝试加入数组并将其转换为字符串和东西,但我似乎无法得到它。我想我可能没有足够的语法知识,这就是我被困的原因。

def combs(a):
    if len(a) == 0:
        return [[]]
    cs = []
    for x in combs(a[1:]):
        cs = cs + [x, x+[a[0]]]
    return cs

a = ["J","a","m","e","s"]
c = combs(a[::-1])

arr = []

for element in c:
    arr.append(element)
print(arr)

#I would like to do this to the 'arr' array please.
#Everything else works how I would like it to.

我只想将1d数组中的所有可能组合作为字符串元素。

arr = [ ['a' , 'b' , 'c'] , ['x' , 'y' , 'z'] ]

for index, i in enumerate(arr):
    arr[index] = ''.join(i)

print(arr)

缩短版:

arr = [''.join(i) for i in arr]
print(arr)
