在pyspark中有没有通用的函数来查找列名？

from pyspark.sql import SparkSession

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

# 创建示例DataFrame
data = [("Alice", 25), ("Bob", 30), ("Charlie", 35)]
df = spark.createDataFrame(data, ["name", "age"])

# 获取列名
column_names = df.columns

# 打印列名
for name in column_names:
    print(name)

name
age
