Passing a pandas dataframe object into a function
提问by Obabs
I have dataframe objects that I would like to to pass into a function.
我有我想传递给函数的数据帧对象。
x = pd.Dataframe()
def function(z):
"code"
return result
result = function(x)
I'm new to python, can someone please steer me in the right direction.
我是python的新手，有人可以引导我朝着正确的方向前进。

Below I am showing a simple function that would have the input parameter as a DataFrame object, and it would check if one of the columns has the String "Some", if so, it returns the Boolean results.
下面我展示了一个简单的函数，它将输入参数作为一个 DataFrame 对象，它会检查其中一列是否有字符串“Some”，如果有，它返回布尔结果。
Check if this helps.
检查这是否有帮助。
x = pd.DataFrame([[1,'Some Text'],[2,'New Text']],columns=('SINO','String_Column'))
def function(z):
l_local_df = z['String_Column'].str.contains('Some')
return l_local_df
result = function(x)
print result
