在Python中,类型转换是将一个数据类型的值转换为另一个数据类型的过程。Python中有多种类型转换函数可用。
以下是一些示例:
1. 将字符串转换为整数:
string_num = "123"
integer_num = int(string_num)
print(integer_num) # 输出:123
2. 将整数转换为浮点数:
integer_num = 123
float_num = float(integer_num)
print(float_num) # 输出:123.0
3. 将浮点数转换为字符串:
float_num = 3.14
string_num = str(float_num)
print(string_num) # 输出:"3.14"
4. 将列表转换为元组:
list_of_numbers = [1, 2, 3, 4, 5]
tuple_of_numbers = tuple(list_of_numbers)
print(tuple_of_numbers) # 输出:(1, 2, 3, 4, 5)
5. 将元组转换为列表:
tuple_of_numbers = (1, 2, 3, 4, 5)
list_of_numbers = list(tuple_of_numbers)
print(list_of_numbers) # 输出:[1, 2, 3, 4, 5]
