python里有没有办法将列表按照模板生成字符串列表？

Answer 1

years=['2016','2014','2013','2009','2005']
msg = ['This year is %s' % k for k in years]
print msg

这个正好算是Python语言精练的一个特点了：可以很容易根据已有的“容器”构建新的“容器”。容器指的是list/tuple/dict/iter 之类的实现了__iter__方法的类型。

比如想要构建字典:

print {k: int(k) for k in years}  # 该写法在Python2.7以后支持
# 输出: {'2014': 2014, '2016': 2016, '2005': 2005, '2013': 2013, '2009': 2009}

Answer 2

years = ['2016', '2014', '2013', '2009', '2005']
msg = map(lambda a: "This year is {0}".format(a), years)
print(msg)
