IndentationError: unindent does not match any outer indentation level

def instrument4(id,ntl=1,curR='CNY',*args):
    pv=0
for n in args:
        pv=pv+n
    print('id:',id)
    print('notional:',ntl)
    print('reporting currency:',curR)
    print('present value:',pv*ntl)
instrument3('MM1001',1000,'USD',1,2,3)

报错显示：
  print('id:',id)
  ^
IndentationError: unindent does not match any outer indentation level

但是之前也是这个程序，都能运行
def instrument3(id,ntl=1,curR='CNY'):
print('id:',id)
print('notional:',ntl)
print('reporting currency:',curR)
instrument3('MM1001',curR='USD',ntl=1000)

求帮忙，到底是哪里的问题啊？

这个应该是缩进格式问题，把所有的缩进检查一下，都改成空格
