Python–迭代字典中的元组
在本文中，我们将讨论如何在 Python 中迭代字典中的元组。
方法 1:使用索引
我们可以通过使用索引来获取特定的元组:
语法:
dictionary_name[index]
迭代特定索引中的整个元组值
for i in range(0, len(dictionary_name[index])):
print(dictionary_name[index][i]
示例:
计算机编程语言
# Ininitalizing a dictionary
myDict = {1: ("Apple", "Boy", "Cat"),
2: ("Geeks", "For", "Geeks"),
3: ("I", "Am", "Learning", "Python")}
print("Tuple mapped with the key 1 =>"),
# Directly printing entire tuple mapped
# with the key 1
print(myDict[1])
print("Tuple mapped with the key 2 =>"),
# Printing tuple elements mapped with
# the key 2 one by one
for each in myDict[2]:
print(each),
print("")
print("Tuple mapped with the key 3 =>"),
# Accessing tuple elements mapped with
# the key 3 using index
for i in range(0, len(myDict[3])):
print(myDict[3][i]),
输出:
Tuple mapped with the key 1 =>
('Apple', 'Boy', 'Cat')
Tuple mapped with the key 2 =>
Geeks
For
Geeks
Tuple mapped with the key 3 =>
I
Am
Learning
Python
方法 2:使用 values()方法
我们可以使用 dictionary.values() 循环遍历字典中的元组
语法:
for i in dictionary_name.values():
for j in i:
print(j)
print(" ")
示例:
Python 3
# Ininitalizing a dictionary
myDict = {1: ("Apple", "Boy", "Cat"),
2: ("Geeks", "For", "Geeks"),
3: ("I", "Am", "Learning", "Python")}
# iterate over all tuples using
# values() method
for i in myDict.values():
for j in i:
print(j)
print(" ")
输出:
Apple
Boy
Cat
Geeks
For
Geeks
I
Am
Learning
Python
