如何从PySpark中的多个列创建字典列表，其中key是列名，value是该列的值？

from pyspark.sql import SparkSession

# 创建SparkSession
spark = SparkSession.builder.getOrCreate()

# 创建一个示例DataFrame
data = [("Alice", 25, "Female"), ("Bob", 30, "Male"), ("Charlie", 35, "Male")]
df = spark.createDataFrame(data, ["name", "age", "gender"])

# 从多个列创建字典列表
dict_list = df.select(*[df[col] for col in df.columns]).rdd.map(lambda row: row.asDict()).collect()

# 打印字典列表
for d in dict_list:
    print(d)

{'name': 'Alice', 'age': 25, 'gender': 'Female'}
{'name': 'Bob', 'age': 30, 'gender': 'Male'}
{'name': 'Charlie', 'age': 35, 'gender': 'Male'}
