如何在pyspark中比较数据帧之间的差异

from pyspark.sql import SparkSession

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

# 创建第一个数据帧
data1 = [("Alice", 25), ("Bob", 30), ("Charlie", 35)]
df1 = spark.createDataFrame(data1, ["Name", "Age"])

# 创建第二个数据帧
data2 = [("Alice", 25), ("Charlie", 35), ("Dave", 40)]
df2 = spark.createDataFrame(data2, ["Name", "Age"])

# 比较两个数据帧之间的差异
diff_df = df1.subtract(df2)

# 显示差异数据帧的内容
diff_df.show()

+-----+---+
| Name|Age|
+-----+---+
|  Bob| 30|
+-----+---+
