Question

所以我从pylint得到一个语法错误，我相信使用' ='时会出现错误，我的原始代码只使用''，但这给了我错误的答案的问题。我在' ='上尝试了多种变体，但它们都不起作用。 Pylint说错误在第8行，尽管我认为是第7行的错误。如果我只有''它通过了pylint检查。

有什么建议吗？

 def num_doublings(initial_population, final_population):
    """prints how many days it takes for a population to reach a certain 
       number, if the population is doubling daily"""
    current_pop = initial_population
    num_days = 0
    while current_pop < final_population:
        increase = current_pop *= 2
        current_pop = current_pop + increase
        num_days += 1
    return num_days

Answer 1

使用python

无法做到这一点

increase = current_pop *= 2

这是另一种选择

def num_doublings(initial_population, final_population):
    """prints how many days it takes for a population to reach a certain 
       number, if the population is doubling daily"""
    current_pop = initial_population
    num_days = 0
    while current_pop < final_population:
        current_pop *= 2
        increase = current_pop
        current_pop = current_pop + 
        num_days += 1
    return num_days

在pylint中获取语法错误
