dict = {'name':'ngy','age':23,'height':180}

1. 最简单的方式：

print(dict)

结果：

{'name': ngy, 'age': 23, 'height': 180}

dict是无序的，若想有序打印，将其转化为list排序，

按key值排序，然后可以用PrettyTable输出：

list = sorted(dict.items(), key = lambda d:d[0])
 
table = PrettyTable(["key","value"])
table.align["key"] = "l"
table.padding_width = 1
for tup in list:
	table.add_row([tup[0], tup[1]])
 
print(table)

按value值排序：

list = sorted(dict.items(), key = lambda d:d[1])

2. 逐个打印key：

for key in dict.keys():
    print('key = {}'.format(key))

结果：

key = name

key = age

key = height

3. 逐个打印value：

for value in dict.values():
    print('value = {}'.format(value))

结果：

value = ngy

value = 23

value = 180

4. 逐个打印key:value:

for key,value in dict.items():
    print('{key}:{value}'.format(key = key, value = value))

结果：

name:ngy

age:23

height:180
