以下是我编写的代码。它说列表分配指数超出范围。我似乎无法弄清楚我在哪里出错了。也许有人可以详细说明错误的位置。
matrix = [[0 for i in range(x)] for j in range(y)]
turns = x
i = 0
j = 0
while turns > 0:
while i < x:
while j < y:
matrix[i][j] = int(raw_input("Enter Array values"))
j += 1
j = 0
i += 1
turns -= 1
print(matrix)
###编辑###########我解决了问题
def generator(x,y):
x = int(raw_input("Enter array length"))
y = int(raw_input("Enter array width"))
print(generator(x, y))
return 0
def main():
Total: <span id="totalPrice">£154.67</span>
<br>
<form>
<input id="DebitCard" type="radio" name="payment" checked>
<label for="DebitCard">Debit Card</label>
<br>
<input id="CreditCard" type="radio" name="payment">
<label for="CreditCard">Credit Card (2% extra)</label>
<br>
</form>
main()的
答案 0 :(得分:0)
如果您尝试以下代码段:
x = []
x[0] = 4
您会看到有错误。原因是x[0]
尚未定义,因此无法修改。要修复错误,您必须在修改错误之前将其附加到列表中:
def genarator(x, y):
square = x * y
matrix = [[]]
matrix2 = []
i = 0
while square > 0:
matrix.append([])
j = 0
while x > j:
matrix[-1].append(int(raw_input("Enter the matrix number")))
j = 1
i = 1
square = -square
matrix2 = matrix2 + matrix
return matrix2
我还修改了索引,因为-1
将为您提供最后一项,这就是您想要的。
