>>> print "I'm %s" % ("jihite") I'm jihite
二、打印整数
>>> print "I'm %d years old" % (17) I'm 17 years old
三、打印浮点数
>>> print "π=%f" % (3.1415926) π=3.141593
四、打印浮点数(指定保留小数点位数)
>>> print "π=%.3f" % (3.1415926) π=3.142
五、指定占位符宽度
>>> print "NAME:%8s AGE:%8d WEIGHT:%8.2f" % ("jihite", 17, 62.2) NAME: jihite AGE: 17 WEIGHT: 62.20
六、指定占位符宽度(左对齐)
>>> print "NAME:%-8s AGE:%-8d WEIGHT:%-8.2f" % ("jihite", 17, 62.2) NAME:jihite AGE:17 WEIGHT:62.20
七、指定占位符(只能用0当占位符)
>>> print "NAME:%-8s AGE:%08d WEIGHT:%08.2f" % ("jihite", 17, 62.2) NAME:jihite AGE:00000017 WEIGHT:00062.20
八、科学计数法
>>> format(0.0000023, '.2e') '2.30e-06' >>> format(0.23, '.2e') '2.30e-01'
