如何在pyspark中通过列名映射值

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

spark = SparkSession.builder.appName("Column Mapping").getOrCreate()

data = [("Alice", 25), ("Bob", 30), ("Charlie", 35)]
df = spark.createDataFrame(data, ["Name", "Age"])

column_mapping = {
    "Name": "姓名",
    "Age": "年龄"
}

for old_col, new_col in column_mapping.items():
    df = df.withColumnRenamed(old_col, new_col)

df.show()
