Python 代碼循環遍歷每個循環有 2 個變量的列表

Question

我試圖了解如何添加 2 個變量列表並讓 python 代碼循環通過它，就像循環一樣

例如

[[1, 9], [2, 9], [3, 7],[4. 6],[5, 9],[6, 9]]

在下面的示例中，它的12,9將使用 12 填充 M 並且它將遍歷代碼 9 次，因此使長度 = 9 然后在完成后移動到下一次迭代 2,9 等

#This is how many iterations are needed
  list = [1,2,3,4,5,6,7,8,9]


# Getting length of list 
   length = len(list) 
   i = 0

   # Iterating using while loop 
     while i < length: 

   #This is the ID    
     m = '12'

Answer 1

我認為你正在嘗試做這樣的事情：

mylist = [[1, 9], [2, 9], [3, 7], [4, 6], [5, 9], [6, 9]]

for first, second in mylist:
    M = first
    for i in range(second):
        print(f'The ID is {M}, iteration number {i}')

The ID is 1, iteration number 0
The ID is 1, iteration number 1
The ID is 1, iteration number 2
The ID is 1, iteration number 3
The ID is 1, iteration number 4
The ID is 1, iteration number 5
The ID is 1, iteration number 6
The ID is 1, iteration number 7
The ID is 1, iteration number 8
The ID is 2, iteration number 0
The ID is 2, iteration number 1
The ID is 2, iteration number 2
The ID is 2, iteration number 3
