替换Pyspark Dataframe中列中的空值

from pyspark.sql import SparkSession

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

# 创建示例DataFrame
data = [("Alice", 25, None), ("Bob", None, 80), ("Charlie", 30, 90)]
df = spark.createDataFrame(data, ["Name", "Age", "Score"])

# 替换空值
df_filled = df.fillna({"Age": 0, "Score": 0})

# 显示替换后的DataFrame
df_filled.show()

+-------+---+-----+
|   Name|Age|Score|
+-------+---+-----+
|  Alice| 25|    0|
|    Bob|  0|   80|
|Charlie| 30|   90|
