控制权转移到下一个条件评估器:elif income < 30000。这个评估为True,因此块#2被执行,因此,Python 在整个if/elif/elif/else子句之后恢复执行(我们现在可以称之为if子句)。if子句之后只有一条指令,即print调用,它告诉我们我今年将支付3000.0的税款(15,000 * 20%)。请注意,顺序是强制性的:if首先出现,然后(可选...
int() 函数支持将不同进制的字符串转换为十进制整数。主要的进制包括: 二进制(以 '0b' 或 '0B' 开头) 八进制(以 '0o' 或 '0O' 开头) 十六进制(以 '0x' 或 '0X' 开头) 你可以根据需要选择不同的进制进行转换。 binary_str = '0b101010' decimal_num = int(binary_str, 2) print(decim...
