20170327 -- 字符串格式化 && 简单lambda函数

###############  HELLO THIS IS MY  CODE  ######################

### 格式化字符串

 

s = "{0} is {1}"   ##### 占位符必须从0 开始，按顺序排

c = s.format('zrz','goodman')

print (c)

 

######### eg2 #######

s = "{name} is {sth}"

c = s.format(name='zrz',sth='goodman')

print(c)

 

########## eg3 ##############

 

s = "{0} is {1}"

c = ['zrz','goodman']

d = s.format(*c)

print(d)

 

########## eg4 ############

 

s = "{name} is {sth}"

c = {'name':zrz,'sth':sb}

d = s.format(**c)

print (d)

###########   简单lambda 函数  ###########

def sum(a) :

　　a += 1

      return a

c = sum(2)

print (c)

 

########## lambda ################

func = lambda a,b : (a+1)*b

c = func(1,2)

print (c)
