在pyspark中更改列名

from pyspark.sql import SparkSession

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

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

# 更改列名
df = df.withColumnRenamed("name", "new_name")

# 显示结果
df.show()

+---------+---+
|new_name |age|
