打印DataFrame名称

使用globals()并搜索与局部变量匹配的对象data

#### Test Code ####
# Import pandas module
import pandas as pd

# Create DataFrame
df = pd.DataFrame({"A":[1,2,3], "B":[10,20,30]})

# Define Function
def test(data):
    name =[x for x in globals() if globals()[x] is data][0]
    print("Dataframe Name is: %s" % name)
    print(data.describe())

# Run Function
test(df)

结果将是:

Dataframe Name is: df
         A     B
count  3.0   3.0
mean   2.0  20.0
std    1.0  10.0
min    1.0  10.0
25%    1.5  15.0
50%    2.0  20.0
75%    2.5  25.0
max    3.0  30.0
