# Tuple(元素组)是不可变的列表
tuple1 = (1, 2, 3)
print tuple1
tuple2 = (tuple1, 4, 5, 6) # 一个元素组可以作为另外一个元素组的元素
print tuple2 # 并且能够在存储的时候保持原始的逻辑关系
for ele in tuple2:
print ele
print '\n'
for ele in tuple2[0]:
print ele
print '\n'
# 元素组与格式化输出
age = 22
name = 'Ning'
print '%s is %d years old.' % (name, age)
print 'Hello, %s' % name # 一个元素的时候可以不用元素组
