Pandas column access w/column names containing spaces

How would I deal with this? The variable "residual sugar" has a space, other than don't use variables with spaces (not my data).
plt.plot(trimmedWine.density, trimmedWine.residual sugar, 'bo', alpha=.25)
I suppose you are referring to pandas data frame column, if so, then trimmedWine['residual sugar'] is what you probably need.

I am trying to put a condition to print the revenue which is greater or equal to certain number using Pandas in Python.
I am using the code line" df[df.Total Revenue>=6678690.38]"
I am getting the error "SyntaxError: invalid syntax." beacuse its not taking my column name(Total Revenue) with space. So how to read column if the column header is with space?
Note = df is where I am reading my file
this should work
df[df['Total Revenue']>=6678690.38]

I have a dataframe, df. One of the column is Text. I want to search the dataframe where the text contains ABC.
Hence, I write the code:
df["Text"].str.contains("ABC")
Now, I want to search which text contains ABC or XYZ.
What will be the syntax?
Using the | pipe is what you need
DF['Text'].str.contains('ABC|XYZ')
DF['Text'].str.contains('ABC') | DF['Text'].str.contains('XYZ')

Hi I am trying to get the opposite values to between
I get a few data of this way:
x[x.between(x.quantile(0.25), x.quantile(0.75))]
But I need the opposite data, how can get it?
Thanks
You can use the ~ to negate.
x[~x.between(x.quantile(0.25), x.quantile(0.75))]

Is it possible to manipulate a variable, for example:
file = "/Python/work.txt"
to just list work.txt, without /Python? excluding everything on the left of the "/"?
Thank you
Of course! Simply do this:
file = "/Python/work.txt"
excluded = file.split("/")[-1]
This would return "work.txt" in the excluded variable.

How can you dynamically create variables? [duplicate]

Closed 8 years ago.
if one had a list of strings, how could they create variables (empty list objects) with those names?
pre_vars= ['list_1','list_2','list_3']
print list_1,list_2,list_3
>>> [],[],[]
I saw some examples that were similar but they were using classes. Can this be done without using classes?
Use globals():
for name in pre_vars:
globals()[name]= []
