- #字符串拼接
- #str.join(元组, 列表, 字典, 字符串) 之后生成的只能是字符串.
- str = "-";
- seq = ("a", "b", "c"); # 字符串序列
- sqr=['a','b','c','sss']#list
- ssr=str.join(sqr)
- print('='.join(ssr))
- print (str.join(sqr));
- print (str.join(seq));
- seq = {'hello':'nihao','good':2,'boy':3,'doiido':4}# 对象
- print('-'.join(seq))
- # 打印字符
- print ("His name is %s"%("Aviad"))#1. 打印字符串
- #http://www.cnblogs.com/plwang1990/p/3757549.html
- print ("He is %d years old"%(25))#2. 打印整数
- print ("His height is %f m"%(1.83))#3. 打印浮点数
- print ("His height is %.2f m"%(1.83))#4. 打印浮点数 (指定保留小数点位数)
- print ("Name:%10s Age:%8d Height:%8.2f"%("Aviad",25,1.83))#5. 指定占位符宽度
- print ("Name:%-10s Age:%-8d Height:%-8.2f"%("Aviad",25,1.83))#6. 指定占位符宽度 (左对齐)
- print ("Name:%-10s Age:%08d Height:%08.2f"%("Aviad",25,1.83))#7. 指定占位符 (只能用 0 当占位符?)
