在for循环中为pyspark dataframe创建动态名称

dataframes = {}
df_names = []

for i in range(5):
    df_name = "df_" + str(i)
    df_names.append(df_name)

for df_name in df_names:
    eval(df_name + " = spark.createDataFrame([(1, 'A'), (2, 'B'), (3, 'C')], ['id', 'value'])")
    dataframes[df_name] = eval(df_name)

for df_name in df_names:
    df = dataframes[df_name]
    df.show()
