1.多行格式化输出
（1）
1 # Author:larlly 2 name = input("input your name :") 3 age = input("input your age :") 4 job = input("input your job :") 5 salary = input("input your salary :") 6 7 info = ''' 8 ----------info of {_name}-------------- 9 Name:{_name} 10 Age:{_age} 11 job:{_job} 12 salary:{_salary} 13 '''.format(_name=name, 14 _age=age, 15 _job=job, 16 _salary=salary) 17 print(info)
（2）
# Author:larlly
name = input("input your name :")
age = input("input your age :")
job = input("input your job :")
salary = input("input your salary :")
info = '''
----------info of %s--------------
Name:%s
Age:%s
job:%s
salary:%s
''' %(name,name,age,job,salary)
print(info)
（3）
1 # Author:larlly 2 name = input("input your name :") 3 age = input("input your age :") 4 job = input("input your job :") 5 salary = input("input your salary :") 6 7 info = ''' 8 ----------info of {0}-------------- 9 Name:{0} 10 Age:{1} 11 job:{2} 12 salary:{3} 13 '''.format(name,age,job,salary) 14 print(info)
（4）
# Author:larlly
name = input("input your name :")
age = input("input your age :")
job = input("input your job :")
salary = input("input your salary :")
info = """
----------info of ''' + name +'''--------------
Name:'''+ name +'''
Age:'''+ age +'''
job:'''+ job +'''
salary:'''+ salary +
""".format(name,name,age,job,salary)
print(info)
2.字符创格式化输出
（1）# Author:larlly'''#打印字符串
print ("his name is %s " %("a"))
#打印整数
print ("he is %d years old" %(25))
#打印浮点数
print ("his height is %f m" %(1.68))
#打印浮点数（指定保留小数点位数）
print ("his height is %.2f m"%(1.69))
#指定占位符宽度
print ("name:%10s age:%8d height:%8.2f"%("abc",25,1.69))
#指定占位符宽度（左对齐）
print("name:%-10s age:%-8d height:%-8.2f"%("abc",25,1.69))
#指定占位符（只能用0当占位符）
print ("name:%-10s age:%08d height:%08.2f"%("abc",25,1.69))
#科学计数法
print(format(0.0015,'.2e'))
（2）字符串里面的%是一个普通字符需要转义，用%%来表示一个%：
print("磁盘使用率：%d %%"% 7)
屏幕输出：如下
磁盘使用率：7 %
