Question

我创建了一个课程：

class aTest:
    name = ""
    twoGroups = -1
    continuous = -1
    parametric = -1
    covariates = -1
    paired = -1

    def __init__(self, name, twoGroups, continuous, parametric, covariates, paired):
        self.name = name
        self.twoGroups = twoGroups
        self.continuous = continuous
        self.parametric = parametric
        self.covariates = covariates
        self.paired = paired

然后创建一个类实例列表：

testList = []
testList.append(aTest("independent samples t-test", 1, 1, 1, 0, 0))
testList.append(aTest("dependent samples t-test", 1, 1, 1, 0, 1))
testList.append(aTest("Mann-Whitney U-test", 1, 1, 0, 0, 0))
testList.append(aTest("Wilcoxson matched pairs test", 1, 1, 0, 0, 1))
testList.append(aTest("one-way independent ANOVA", 0, 1, 1, 0, 0))
testList.append(aTest("Kruskall-Wallis test", 0, 1, 0, 0, 0))
testList.append(aTest("one-way repeated measures ANOVA", 0, 1, 1, 0, 1))
testList.append(aTest("Friedman's ANOVA", 0, 1, 0, 0, 1))
testList.append(aTest("ANCOVA", 0, 1, 1, 1, 0))

然后，最后，我尝试删除列表中属性parametric等于0的所有项目：

print("Now, remove the nonparametric tests...")
for test in testList:
    if test.parametric == 0:
        testList.remove(test)

print("...and print what's left, with confirmation the attribute was 0")
for test in testList:
    print(test.name+", "+str(test.parametric))

我在控制台中得到以下结果：

> Now, remove the nonparametric tests... 
> ...and print what's left, with confirmation the attribute was 0
> independent samples t-test, 1
> dependent samples t-test, 1
> Wilcoxson matched pairs test, 0
> one-way independent ANOVA, 1
> one-way repeated measures ANOVA, 1
> ANCOVA, 1

Wilcoxson matched pairs test命名对象发生了什么事？

list .remove（）函数如何工作？
