字符串格式化输出定义

1.加号拼接：

name = input("name:")age = input("age:")job = input("job:")message = '''---------information of ''' + name +'''----------name:''' + name + '''age:''' + age + '''job:''' + jobprint(message)----------information of zhoumingkang----------name:zhoumingkangage:30job:itProcess finished with exit code 0

2.%s格式化字符串

name = input("name:")age = int(input("age:"))     #强制将字符串转为×××print(type(age))             #打印变量类型，以确定是否正确job = input("job:")message1 = '''----------information of %s----------name:%sage:%d             #%d代表整型job:%s''' % (name,name,age,job)print(message1)

3.{}格式化字符串

name = input("name:")age = input("age:")job = input("job:")message2 = '''----------information of {_name}----------name:{_name}age:{_age}job:{_job}'''.format(_name=name,_age=age,_job=job)还有另外一种大括号格式化字符串方法：message3 = '''----------information of {0}----------name:{0}age:{1}job:{2}'''.format(name,age,job)print(message3)

备注：

当使用‘’‘%s’‘’时，后面接在用%(变量名)

4.简单的格式化字符串输出

name = input("name:")age = input("age:")job = input("job:")print('my name is {0}, age is  {1}，job is {2}'.format(name,age,job))输入结果：name:kangage:30job:itmy name is kang, age is  30，job is it
