它在我的程序中早些时候作为变量名工作,现在突然之间,Python 在我的程序中不断返回字母“n”作为无效语法。
知道为什么,以及如何解决这个问题吗?
bad_input=True
while bad_input:
bad_input=False
User_Choice=int(input('Which frame would you like to choose(1,2,3 represent positive selections, 4,5,6 represent -1,-2, and -3 respectively')
n = 3
if User_Choice== int(1):
Chunks=[RNA_Comp[i:i+n] for i in range(0, len(RNA_Comp), n)]
if User_Choice== int(2):
Chunks=[RNA_Comp[i:i+n] for i in range(1, len(RNA_Comp), n)]
if User_Choice== int(3):
Chunks=[RNA_Comp[i:i+n] for i in range(2, len(RNA_Comp), n)]
else:
print('Please select an integer value from 1 to 6')
bad_input=True
