python字典

# 创建字典
d1={'jack1':'values1','jack2':'values2','jack3':'values3','jack4':'values4','jack5':'values5'}
d2={'jack1':'values1','jack2':'values2','jack7':'values7','jack8':'values8','jack9':'values9'}
# 获取字典中values
print(d1['jack3'])

#循环输出字典中的key
for k in d1.keys():
    print(k)

#循环输出字典中的values
for v in d1.values():
    print(v)
    
#循环输出字典中的key,values
for k,v in d1.items():
    print(k,v)

#删除字典中某个值
del d1['jack1']
print(d1)

#清空整个字典
d1.clear()
print(d1)
