Python – 遍历字典中的元组

在本文中，我们将讨论如何在Python中迭代字典中的元组。

方法一：使用索引

我们可以通过使用索引来获取特定的元组：

句法：

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]

例子：

Python

# Initializing 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() 用 for 循环遍历字典中的元组

句法：

for i in dictionary_name.values():
  for j in i:
      print(j)
  print(" ")

例子：

Python3

# Initializing 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
