⑴ redhat yum安装报错python(abi) = 2.4 is needed by...

试一下安装RPM Forge epel release 6。

⑵ linux下安装yum时报错需要python(abi)=2.4请问怎么处理

yum应该已经有了。或者是yum2。
从提示上看。你没有安装python，也没有安装python-elementtree这个库。

安装一下再继续试试看。

⑶ Python3.3里面，s.isdigit和s.isnumeric有什么区别求举例

num = "1" #unicode
num.isdigit() # True
num.isdecimal() # True
num.isnumeric() # True

num = "1" # 全角
num.isdigit() # True
num.isdecimal() # True
num.isnumeric() # True

num = b"1" # byte
num.isdigit() # True
num.isdecimal() # AttributeError 'bytes' object has no attribute 'isdecimal'
num.isnumeric() # AttributeError 'bytes' object has no attribute 'isnumeric'

num = "IV" # 罗马数字
num.isdigit() # True
num.isdecimal() # False
num.isnumeric() # True

num = "四" # 汉字
num.isdigit() # False
num.isdecimal() # False
num.isnumeric() # True

===================
isdigit()
True: Unicode数字，byte数字（单字节），全角数字（双字节），罗马数字
False: 汉字数字
Error: 无

isdecimal()
True: Unicode数字，，全角数字（双字节）
False: 罗马数字，汉字数字
Error: byte数字（单字节）

isnumeric()
True: Unicode数字，全角数字（双字节），罗马数字，汉字数字
False: 无
Error: byte数字（单字节）

================
import unicodedata

unicodedata.digit("2") # 2
unicodedata.decimal("2") # 2
unicodedata.numeric("2") # 2.0

unicodedata.digit("2") # 2
unicodedata.decimal("2") # 2
unicodedata.numeric("2") # 2.0

unicodedata.digit(b"3") # TypeError: must be str, not bytes

⑸ 怎样用python算24点

这个参考一下：是csdn的
输入4个数字, 输出所有用加减乘除结果为24的表达式. 代码如下:

def isEqual(num1, num2):
return
abs(num1 - num2) < 1e-5;
# End of isEqual().
