２次元配列を３次元配列にできない

Question

with open('path') as f:
a = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
b = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
c = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
d = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
e = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
f = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
g = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
h = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
i = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
j = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
k = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
l = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
m = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
n = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
o = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

with open('path') as f:
p = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

q=np.stack([a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p],0)

paθの部分は自分のパソコンのファイルを開くためのpathになっています。
このようにJupyterで複数の２次元配列のテキストファイルを開いて、stackで３次元配列にしたいのですが、

all input arrays must have the same shape

というエラーが出て、３次元配列にすることができません。

a~pまで1つずつ試したところ、6個目のfのテキストファイルのみ３次元配列にできないです。

テキストファイルの２次元配列は全て大きさが同じなので、なぜこのように出てしまうのかわかる方いらっしゃったら教えていただきたいです。

Answer 1

with open('path') as f:
f = [list(map(lambda x:int(x), i.split())) for i in f.read().splitlines()]

でfを書き換えているからです。

with open('path') as file:
f = [list(map(lambda x:int(x), i.split())) for i in file.read().splitlines()]

などに変更しましょう。
