Eine Zusammenfassung sehr praktischer Python-Tipps

import uuid
mac = uuid.uuid1().hex[-12:]
print(mac)

a = ['b','c','d']
del a[0]
print(a)# 输出 ['c', 'd']

a = ['b','c','d']
del a[0:2] # 删除从第1个元素开始，到第2个元素
print(a)# 输出 ['d']

a = ['b','c','d']
del a
print(a) # 此时a未定义

a = ['c','d']
a.reverse()
a = ['d','c']
b = ','.join(a)
print(b) # 输出 d,c

import random
x = random.randint(1,100)
y = random.choice( 'abcd')
print(x)
print(y)

a=[1,2,3]
b=['a','b','c']
c=dict(zip(a,b))
print(c) # 输出： {1:'a',2:'b',3:'c'}

a='1-2-3-4'
b=map(int,a.split('-'))
print(b) # 输出： [1,2,3,4]

a = str.decode( 'utf-8' )
b = str.encode( 'utf-8' )
str.isdigit() # 是否数值
str1 = 'abc%s'%str2

import string
x= string.ascii_lowercase
# print(x) # 输出： abcdefghijklmnopqrstuvwxyz
d = enumerate( x )
c = list( d )
print(c)
