print('name: {name},version: {version},code: {code}' %{'name':'Python','version':3.6 ,'code':3})

Python字符串格式化

#{}  不能重复  有序
res = 'name: {},version: {},code: {}'.format('Python','3.6',3)
#{0} 可以重复  有序
res1 = 'name: {0},version: {1},code: {1}.{0} is an easy to learn'.format('Python','3.6',3)
#{name} 键值对 无序
res2 = 'name: {name}, version: {version}, code: {name} {code}.is an easy to learn'.format(name = 'Python',version = '3.6',code = 3)
print(res)
print(res1)
print(res2)
