使用Python内置函数:bin()、oct()、int()、hex()可实现进制转换。

先看Python官方文档中对这几个内置函数的描述:
bin(x)Convert an integer number to a binary string. The result is a valid Python expression. If x is not a Python int object, it has to define an __index__() method that returns an integer.
oct(x)Convert an integer number to an octal string. The result is a valid Python expression. If x is not a Python int object, it has to define an __index__() method that returns an integer.

int([number | string[, base]])Convert a number or string to an integer. If no arguments are given, return 0. If a number is given, return number.__int__(). Conversion of floating point numbers to integers truncates towards zero. A string must be a base-radix integer literal optionally preceded by ‘+’ or ‘-‘ (with no space in between) and optionally surrounded by whitespace. A base-n literal consists of the digits 0 to n-1, with ‘a’ to ‘z’ (or ‘A’ to ‘Z’) having values 10 to 35. The default base is 10. The allowed values are 0 and 2-36. Base-2, -8, and -16 literals can be optionally prefixed with 0b/0B, 0o/0O, or 0x/0X, as with integer literals in code. Base 0 means to interpret exactly as a code literal, so that the actual base is 2, 8, 10, or 16, and so that int('010', 0) is not legal, while int('010') is, as well as int('010', 8).
hex(x)Convert an integer number to a hexadecimal string. The result is a valid Python expression. If x is not a Python int object, it has to define an __index__() method that returns an integer.

Python,内置,函数,进制,转换,的,用法,使用,Pyt计数多个单元格范围:(A1:A0,C1:C10)。
如下图:二、Count函数这个函数用于计算单元格数的:=COUNT()=计数(A1:A10)。
如下图:三、Average函数Average用于计算平均值:=AVERAGE()例如,计算多个单元格的平均值:=平均值(A1:A10)。
如下图:四、IF函数IF函数用于判断条件,然后根据判断结果返回指定值。
IF函数公式为:=IF(逻辑判断,结果为TRUE,结果为FALSE)。
例如,给定条件为A1>A5。
如果比较结果为TRUE。
IF函数返回第二个参数的值;
如果为FALSE,则返回第三个参数的值=If(A1>A5,1,2)。
如下图:五、VLOOKUP函数VLOOKUP函数用于查找表中的数据。
该函数的语法公式为:=VLOOKUP(搜索值,区域,要返回的列,1近似匹配0精确匹配)。
如下图:六、NOW函数和TODAY函数NOW函数返回日期和时间。
TODAY函数仅返回日期。
NOW函数和TODAY函数没有参数,只有一对括号:=NOW()=TODAY()比方说,一个项目今天进行了多少天=today()-开始日期。
获得的数字是项目实施的天数。
