week_one-python格式化输出

1.多行格式化输出

（1）

 # 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=age,
            _job=job,
            _salary=salary)
 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）

 # 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 {0}--------------
 Name:{0}
 Age:{1}
 job:{2}
 salary:{3}
 '''.format(name,age,job,salary)
 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 %
