Python的字符串格式化有两种方式: 百分号方式、format方式
一、format方式
test = ‘my name is {},age {}‘ v = test.format(‘alex‘, 19) print(v) # 输出：my name is alex,age 19
test = ‘names is {1},emil{0}‘ v = test.format(‘101@qq.com‘,‘alex‘) print(v) # 输出：names is alice,emil101@qq.com
test = ‘names is {name1},emil{emil1}‘ v = test.format(name1=‘alice‘,emil1=‘101@qq.com‘) print(v) # 输出：names is alice,emil101@qq.com
#传入列表 test = ‘names are {},emil{}‘ v = test.format(*([‘alice‘,‘lili‘],[‘101@qq.com‘,‘www@ww.com‘])) print(v) # 输出：names are [‘alice‘, ‘lili‘],emil[‘101@qq.com‘, ‘www@ww.com‘]
#传入字典 test = ‘names is {name1},emil{emil1}‘ v = test.format(**{‘name1‘:‘alice‘,‘emil1‘:‘101@qq.com‘}) print(v) # 输出：names is alice,emil101@qq.com
二、百分号方式
#%s:可加任意类型的值 %d：加整数 print(‘i am %s my hobby is %s‘ % (‘alice‘,‘Fitness‘)) #输出结果：i am alice my hobby is Fitness print(‘i am %s my age is %d‘ % (‘alice‘,19)) #输出结果：i am alice my age is 19 #打印浮点数%f print(‘percent %.2f‘%99.333333) #保留小数点后2位 # 输出结果：percent 99.33 print(‘percent %f‘%99.12345689) #默认保留小数点后6位 # 输出结果：percent 99.123457 #打印百分号 print(‘percent %.2f%%‘%99.333333) #保留小数点后两位 # 输出结果：percent 99.33% #字典 print("i am %(name)s age %(age)d" % {"name": "alex", "age": 18}) # 输出结果：i am alex age 18 #打印加空格 print(‘i am %+10s my age is %d‘ % (‘alice‘,19)) #左边加10个空格 # 输出结果：i am alice my age is 19 print(‘i am %-10s my age is %d‘ % (‘alice‘,19)) #右边加10个空格 # 输出结果：i am alice my age is 19 #打印加颜色：\033[88;1m \033[0m print(‘i am \033[45;1m%-10s\033[0m my age is %d‘ % (‘alice‘,19))
#输出结果：
