Python 如何转换元组和列表

首先，我们将看到如何在Python中将元组转换为列表。

将包含整数元素的元组转换为列表

要将元组转换为列表，请使用list()方法并将要转换的元组设置为参数。

示例

让我们看一个示例。

# Creating a Tuple
mytuple = (20, 40, 60, 80, 100)

# Displaying the Tuple
print("Tuple = ",mytuple)

# Length of the Tuple
print("Tuple Length= ",len(mytuple))

# Tuple to list
mylist = list(mytuple)

# print list
print("List = ",mylist)
print("Type = ",type(mylist))

输出

Tuple =  (20, 40, 60, 80, 100)
Tuple Length=  5
List =  [20, 40, 60, 80, 100]
Type =  <class 'list'>

将包含字符串元素的元组转换为列表

要将元组转换为列表，请使用list()方法，并将包含字符串元素的元组设置为要转换的参数。

示例

让我们看一个示例：

# Creating a Tuple
mytuple = ("Jacob", "Harry", "Mark", "Anthony")

# Displaying the Tuple
print("Tuple = ",mytuple)

# Length of the Tuple
print("Tuple Length= ",len(mytuple))

# Tuple to list
mylist = list(mytuple)

# print list
print("List = ",mylist)
print("Type = ",type(mylist))

输出

Tuple =  ('Jacob', 'Harry', 'Mark', 'Anthony')
Tuple Length=  4
List =  ['Jacob', 'Harry', 'Mark', 'Anthony']
Type =  <class 'list'>

将列表转换为元组

要将列表转换为元组，请使用tuple()函数：

示例

# Creating a List
mylist = ["Jacob", "Harry", "Mark", "Anthony"]

# Displaying the List
print("List = ",mylist)

# Convert List to Tuple
res = tuple(mylist)
print("Tuple = ",res)

输出

List =  ['Jacob', 'Harry', 'Mark', 'Anthony']
Tuple =  ('Jacob', 'Harry', 'Mark', 'Anthony')
