[Solved] Reading every nth line into a column from txt file

[snippsat]

If look at data so should it be turn around this is called transpose() if want data into Pandas for calculation, plot..ect.
If just want display data then can Yoriz method work.

To give example,just using first record.

record = {}
with open('ca_data.txt') as f:
    header = next(f)
    for line in f:
        line = line.strip()
        line = line.replace('Time-zero    ', '')
        line = line.split(':')
        line_1 = line[0].strip()
        line_2 = ''.join(line[1:])
        record[line_1] = line_2.split()

# Read like this so it fill in empty values with None
df = pd.DataFrame.from_dict(record, orient='index')
print(df) 

Output:
Lifetimes (ns)    0.4000  0.1250   2.0446
Std deviations    0.0588    None     None
Intensities (%)  69.2721  9.6726  21.0553
Channel number   41.5603    None     None

No can use transpose(),then it will a useful DataFrame.

>>> df = df.transpose()
>>> df
  Lifetimes (ns) Std deviations Intensities (%) Channel number
0         0.4000         0.0588         69.2721        41.5603
1         0.1250           None          9.6726           None
2         2.0446           None         21.0553           None
