python基本数据类型

python-01-输入输出&基本数据类型7-1

jmu-python-输入输出-计算字符串中的数（10

分）a=[]s=0n=input()a=n.split()#str.split(str="",num=string.count(str)).foriina:s=s+float(i)print(len(a))print("{:.3f}".format(s))Python中的spilt方法只能通过指定的某个字符分割字符串，如果需要指定多个字符，需要用到re模块里的split方法。importres=input()x=re.split(r"+",s)print(x)7-2
