dimensions = (200, 5)
print(dimensions[0])
print(dimensions[1])

200

4.5.2遍历元祖中的所有值

dimensions = (200, 5)
for dimension in dimensions:
    print(dimension)

200
5

4.5.3修改元祖变量

dimensions = (200, 5)
print("Original dimensions:")
for dimension in dimensions:
    print(dimension)

dimensions = (400, 100)
print("\nModified dimensions:")
for dimension in dimensions:
    print(dimension)

Original dimensions:
200
5

Modified dimensions:
