如果t，如果== True，有什么区别？

Question

以下返回[1]

def compact(listy):
    truth_list = [t for t in listy if t == True]
    return truth_list

print(compact([0,1,2,"",[], False, {}, None, "All done"]))

以下返回所需的结果，所有真值：[1、2，“全部完成”]

def compact(listy):
    truth_list = [t for t in listy if t]
    return truth_list

print(compact([0,1,2,"",[], False, {}, None, "All done"]))

我对为什么t == True只返回[1]感到困惑
