尝试调用python函数时不断出现语法错误

Question

Can you guys help me out? I've been stuck trying to figure out what I'm doing wrong when calling this function. I have previous examples that, at least to my eyes look exactly the same and work just fine. VSCode claims the syntax error is in the call. I'm sure it's a simple fix but it's driving me mad, Thanks.

lst = [4, 6, 1, 3, 5, 7, 25]

def stars(myList):
    for i in range(0, len(myList - 1)):
        print ("*" * (myList[i])
stars(lst)

Answer 1

There are two errors in the code.

One is the missing parentheses after print ("*" * (myList[i]) that will give bellow error

SyntaxError: invalid syntax

So you need to add parentheses as print ("*" * (myList[i]))

Second is the wrong condition in range.

len(myList - 1) will below error as you cannot subtract from the list directly.

First, you need to get the length by len(myList) then subtract as len(myList) - 1

TypeError: unsupported operand type(s) for -: 'list' and 'int'

Below is the correct code that should work

lst = [4, 6, 1, 3, 5, 7, 25]

def stars(myList):
    for i in range(0, len(myList) - 1):
        print ("*" * (myList[i]))
stars(lst)
