1.获取字典的所有键
info = {‘name‘:‘wdc‘,‘age‘:18,‘gender‘:‘男‘}
# 打印字典的所有键
for i in info.keys():
print(i)
2.获取字典的所有值
info = {‘name‘:‘wdc‘,‘age‘:18,‘gender‘:‘男‘}
# 打印字典的所有值
for i in info.values():
print(i)
3.获取字典的键和值
info = {‘name‘:‘wdc‘,‘age‘:18,‘gender‘:‘男‘}
# 将键和值分别赋给i和j
for i,j in info.items():
print(i,j)
info = {‘name‘:‘wdc‘,‘age‘:18,‘gender‘:‘男‘}
# 将字典的每个键值对生成一个元组
for i in info.items():
print(i)
