Python中有关join的操作

#关于join的操作，join是转化为字符串的操作

# s = "alex"
# s1 = "_".join(s)   #join里面可以放一个可迭代对象(元组、列表、字典、字符串)，“-”表示用什么连接后面的可迭代对象
# s2 = "+".join(s)
# print(s1)
# print(s2)

##列表转换成字符串用join，字符串转换成列表用split  重要!!!!
l = ["tai","ale","wust","egin","发动机"]
list = "".join(l)
print(list)

#将元组转化成字符串
l = ("tai","ale","wust","egin","发动机")
list = "".join(l)
print(list)

#将字典转化成字符串，注意，转化完的是字典的键，将字典的键转化成字符串

l = {"k1":"v","k2":"v2","k3":"v3"}
str = "".join(l)
print(str)
