Python中字符串格式化的细节
1 >>> print("%.2f %s are worth $%d"%(4.5560,"Argentine Pesos",1)) 2 4.56 Argentine Pesos are worth $1 3 >>> template = "%.2f %s are worth $%d" 4 >>> templat % (4.5560,"Argentine Pesos",1) 5 Traceback (most recent call last): 6 File "<pyshell#230>", line 1, in <module> 7 templat % (4.5560,"Argentine Pesos",1) 8 NameError: name 'templat' is not defined 9 >>> template = "%.2f %s are worth $%d" 10 >>> template % (4.5560,"Argentine Pesos",1) 11 '4.56 Argentine Pesos are worth $1'
Python3中,一段代码压缩成一物理行print可直接生成输出结果,如line1,line2。
物理行分解,在字符串格式定义好之后不使用print也可输出结果。
