Option 2: df.isnull().sum().sum() - This returns an integer of the total number of NaN values: This operates the same way as the .any().any() does, by first giving a summation of the number of NaN values in a column, then the summation of those values: df.isnull().sum() ...
# 定义函数check_number def check_number(number): if number % 2 == 0: print("偶数") else: print("奇数") # 调用函数check_number并传递参数 check_number(5) 上述示例中,函数check_number接受一个参数number,判断该参数是否为偶数,并输出相应的结果。通过调用函数check_number并传递参数5,可...
