Python Data Type Conversion Guide

In Python, you can use built-in type conversion functions to convert data types. Here are a few common type conversions:

1. Converts a value to an integer.
2. converts a value to a floating point number
3. Convert to string.
4. create a list
5. Create an empty tuple.
6. Create a dictionary.
7. create a new empty set.

For example, to convert a string to an integer, you can use the int() function.

num_str = "123"
num_int = int(num_str)
print(num_int)  # 输出：123

To convert a number to a string, you can use the str() function.

num_int = 123
num_str = str(num_int)
print(num_str)  # 输出："123"

Please ensure that data is correctly converted to the target type when performing type conversions to avoid errors.
