这是我的代码:
def get_num():
number = int(raw_input(" ")),
print "|"
return number
list_of_letter = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k' 'l' 'm' 'n' 'o' 'p' 'q' 'r' 's' 't' 'u' 'v' 'w' 'x' 'y' 'z']
num = -1
print "welcome to the sudoko maker!!!"
print "I will start asking you information."
for lines in range (9):
for ask in range(9):
if num == 25:
num = 0
num = num + 1
print list_of_letter [num],
print
当我运行它时,python 写道: IndexError: list index out of range 为什么????
