In Python, you can utilize some built-in functions or methods to change data types.

  1. convert to integer
x = 5.5
x = int(x)
print(x)  # 输出：5
  1. convert to a decimal number
x = 5
x = float(x)
print(x)  # 输出：5.0
  1. Convert to a string
x = 5
x = str(x)
print(x)  # 输出："5"
  1. Create a list without any elements.
x = (1, 2, 3)
x = list(x)
print(x)  # 输出：[1, 2, 3]
  1. No words needed.
x = [1, 2, 3]
x = tuple(x)
print(x)  # 输出：(1, 2, 3)
  1. create a collection containing unique items
x = [1, 2, 3, 3]
x = set(x)
print(x)  # 输出：{1, 2, 3}
  1. create a dictionary
x = [("name", "Alice"), ("age", 25)]
x = dict(x)
print(x)  # 输出：{"name": "Alice", "age": 25}

It is important to note that converting between certain data types may result in data loss or inaccuracies. Therefore, it is crucial to be careful when performing data type conversions in order to ensure the reliability of the data conversion.
