python如何取动态变量名的值？-灵析社区
七安前程序结构大体如下 tree_1={...} tree_2={...} ... tree_n={...} 如何通过for循环取出以上变量，并遍历 for i in range(1,n): for item in tree_i: 关键是这个tree_i如何搞
我是张工你呢tree_1 = {'a1': 1, 'a2': 2}
tree_2 = {'a3': 3, 'a4': 4}
tree_3 = {'a5': 5, 'a6': 6}
for i in range(1, 4):
value = eval(f'tree_{i}')
for item in value:
print(item, value[item])
或者
tree_1 = {'a1': 1, 'a2': 2}
tree_2 = {'a3': 3, 'a4': 4}
tree_3 = {'a5': 5, 'a6': 6}
for i in range(1, 4):
value = locals()[f'tree_{i}']
for item in value:
print(item, value[item])
