打印语句影响for循环[关闭]

Question

#Matrix 15x15
matrix = [[0 for _ in range(15)] for _ in range(15)]


print(int(len(matrix)/2)#why running with this causes error

# Printing the matrix
for row in matrix:
    print(" ".join(map(str, row)))#intrepreter points here for where error occured

打印语句在 for 循环中导致错误，如果它被注释为删除了一切都有效。对于上下文，我正在制作一个没有 qr import IN PYTHON 的 QR

Answer 1

右括号

print(int(len(matrix)/2))
