New to python and I keep getting this error when I try running my code. python的新手,当我尝试运行我的代码时,我不断收到这个错误。 This is the code I'm trying to run
这是我试图运行的代码
table=[0]*3
column=0
n=0
with open('matrix.txt','r') as f:
numbers=f.read()
numbers=[int(x) for x in numbers.split()]
for i in range(3):
table[column]=[0]*3
for j in range(3):
table[i][j]=numbers[n]
n+=1
column+=1
print(table)

关于如何解决它的任何想法?
You make it more complicated than it has to be:你让它变得比它更复杂:
numbers = [2, 3, 4, 1, 2, 6, 9, 8, 9]
table = [numbers[i:i+3] for i in range(0, len(numbers), 3)]
You are incrementing the column outside of the outer for loop.您正在增加外部 for 循环之外的列。 Moreover, it is misspelled.
此外,它拼写错误。
how about:怎么样:
import numpy as np
with open('matrix.txt','r') as f:
numbers=f.read()
table =np.array([int(x) for x in numbers.split()]).reshape((3,3))
print(table)
if you really insist that your table is not a numpy array just convert it to a list:如果你真的坚持你的表不是一个 numpy 数组,只需将它转换为一个列表:
table = table.tolist()
