如何在pyspark中实现数据框(而不是数据框列)的“别名”

from pyspark.sql import SparkSession
from pyspark.sql.functions import col

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

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

# 别名示例：将name列的别名设置为"姓名"
df_alias = df.select(col("name").alias("姓名"), col("age"))

# 打印结果
df_alias.show()
