我是
Python新手,我对列表有困难.我希望从列表中的所有值中减去1,除了值10.5.下面的代码给出了x3列表分配索引超出范围的错误.到目前为止的代码：
x2=[10.5,-6.36,11.56,19.06,-4.37,26.56,9.38,-33.12,-8.44,0.31,-13.44,- 6.25,-0.94,-5.94,-13.75,-23.44,-51.68,10.5]
x3=[]
i=0
while (i<22):
if x2[i]==10.5:
x3[i]=x2[i]
else:
x3[i]=x2[i]-1
break
#The result I want to achieve is:
#x3=[10.5,-7.36,10.56,18.06,-5.37,25.56,8.38,-34.12,-9.44,-1.31,-14.44,-7.25,-1.94,-6.94,-14.75,-24.44,-52.68,10.5]
