如何将二维数组中的单词打印到具有均匀空格的网格中？

Question

我正在尝试将不同长度的单词的二维数组打印为网格。

我正在尝试使单词间距均匀。

注意：数组中的单词每次都是随机的。

例子，

arr = [
   ['eighteen', 'twenty-two', 'twenty-one', 'ten', 'twenty-three'], 
   ['eleven', 'thirteen', 'four', 'three', 'twenty'], 
   ['twenty-eight', 'six', 'fourteen', 'seventeen', 'twenty-seven'], 
   ['twenty-four', 'two', 'nine', 'one', 'five'], 
   ['sixteen', 'fifteen', 'twelve', 'twenty-nine', 'seven']]

for i in range(5):
    x = arr[i]
    y = "    ".join(x)
    print(f"\t\t{y}",end="\t")
    print("\n\n")

输出：

    eighteen    twenty-two    twenty-one    ten    twenty-three 


    eleven    thirteen    four    three    twenty   


    twenty-eight    six    fourteen    seventeen    twenty-seven    


    twenty-four    two    nine    one    five   


    sixteen    fifteen    twelve    twenty-nine    seven

但是，我希望它看起来更像这样：

   eighteen       twenty-two       twenty-one         ten         twenty-three 


    eleven         thirteen          four            three           twenty   


 twenty-eight        six            fourteen       seventeen      twenty-seven    


  twenty-four        two              nine            one             five   


    sixteen         fifteen          twelve        twenty-nine        seven

我希望每个单词的中心彼此对齐。

我能做些什么来实现这个目标？

谢谢。

您可以先计算整个数组中的最大字长，然后使用:^{width} format specifier 在该可用宽度内将每个字居中：

width = max(len(word) for line in arr for word in line)
for line in arr:
    print(' '.join(f'{word:^{width}}' for word in line), end='\n\n')
