Python Group by and Sum with a Blank space

Does that help I'm assuming that your empty entries are NaN, if they are not, I advise you to make them NaN. The general idea is to fill foward in your country column, then dropping null values, which places the country code next to each row that contains data, while removing the header row. The groupby + sum is a simple operation from that point.
ffill + dropna + groupby
code :
d = dict(
    Country=df.Country.ffill(),
    Revenue=df.Revenue.str.strip('$').astype(float)
)

df.assign(**d).dropna().groupby('Country')['Revenue'].sum()
Country
AE     12.02
AT      0.09
AU    128.80
FR     26.38
Name: Revenue, dtype: float64

pexpect prompt for blank space in python

will help you Edit:
ss.expect takes any string as a regular expression, and uses it to search the output from a program. In your case, if you want to match the line before all the dashes, you can do
code :
ss.expect(r'TCP window size: .*yte \(default\)')

it should still fix some issue As it is shown, it appears that the blank section you are talking about is coming from the Group Footer of the 2nd Group, not from group1 header.
Waht you have to do is reduce the Group Footers to the minimum size allowed, this will remove your blank space...

Python: Split a list where blank space

With these it helps I believe I have a beginner's question which I haven't been able to find a solution for. Perhaps somebody here knows how to solve it? , Use a list-comp with str.split:
code :
>>> l = ['1 2 3',
...      '4 5 6',
...      '7 8 9']
>>> [r.split() for r in l]
[['1', '2', '3'], ['4', '5', '6'], ['7', '8', '9']]

I wish this helpful for you The spaces you posted in your example are CHAR(63)'s not real spaces: CHAR(32).
I copy/pasted the spaces directly from your post. Note that this: SELECT ASCII(' ') Retutns 63. I copied the spaces into CONCAT like this: SELECT CONCAT('a', ' ' , 'a', ' ' , 'x'); returns: a?a?x
code :
SELECT CONCAT('a', CHAR(32) , 'b', CHAR(32), 'c'); 
SELECT CONCAT('a',Sp,'b',Sp, 'c')
FROM (VALUES(CHAR(32))) AS s(Sp);
SELECT CONCAT_WS(CHAR(32),'a','b','c');

python matplotlib pcolor blank space

I wish this help you What you're seeing is a result of rounding in floating point numbers. The closest number to 0.8 that can be represented as a Python float is 0.80000000000000004. Matplotlib then rounds up to its idea of the next "nice" number at which to place an axis tick mark. You can control this behavior either by setting the axis limits explicitly:
