试图找到一种方法来制作这个 2D 列表。

Answer 1

试试这个：

def main():
    print("Num of rows:")
    row = int(input())
    print("Num of Cols:")
    columns = int(input())
    print("Out:\n")

    for i in range(row): # iterate in rows
        print('x'*columns) # print 'x' columns times

if __name__ == '__main__':
    main()

Answer 2

执行此操作的多种方法之一：

for x in range(row):
    print('x '*col)

例如， row =3 ， col =3然后输出：

x x x 
x x x 
x x x 

---

或者，

创建一个列表-

a=[]
for x in range(0, row):
    a.append(["x"] * col)

然后打印出来——

for row in a:
    print " ".join(row)

Answer 3

这在创建 2048 游戏板时对我有用

# creating a board of 4 x 4 size
# initializes a list of lists with 4 rows and 4 columns
board = [ [0] * 4 ] * 4

# for printing the board
for row in board:
print(row)

# the result it produces
[0, 0, 0, 0]
[0, 0, 0, 0]
[0, 0, 0, 0]
[0, 0, 0, 0]
