python - 仅更新嵌套循环中的整数

Question

swim=[['Cycle Shoes+Goggles', 1.25], 
      ['Cycle shoes+Sunglasses', 1], 
      ['Run shoes+Goggles', 1.33]]

swim_s = 50
    
def update1(lst1):
    for i in lst1:
        i[1]*=swim_s
    
update1(swim)

目前，该程序只会将第一个整数乘以 50，但我将如何对列表中的每个整数执行此操作（完整列表将有超过 10 个整数）

Check if it's an instance of int using isinstance:

def update(lst):
    for ele in lst1:
        for i in range(len(ele)):
            if isinstance(ele[i], int):
                ele[i] *= 50
