1、字符型list转换为string

dat = ['1','2','3','4','5']
str1 = ''.join(dat)

2、整数型list转换为string

dat = [1,2,3,4,5]
str_list = map(str,dat) #方法1
str_list = [ str(i) for i in dat] #方法2
str1 = ''.join(str_list )

3、ASCII的list转化为string

dat = [50, 48, 50, 48, 49, 50, 49, 56]
str_list = map(chr,dat) #方法1
str_list = [ chr(i) for i in dat] #方法2
str1 = ''.join(str_list )
