How do I convert a list of lists to a panda dataframe?
it is not in the form of coloumns but instead in the form of rows.
#!/usr/bin/env python
from random import randrange
import pandas
data = [[[randrange(0,100) for j in range(0, 12)] for y in range(0, 12)] for x in range(0, 5)]
print data
df = pandas.DataFrame(data[0], columns=['B','P','F','I','FP','BP','2','M','3','1','I','L'])
print df
for example:
data[0][0] == [64, 73, 76, 64, 61, 32, 36, 94, 81, 49, 94, 48]
I want it to be shown as rows and not coloumns.
currently it shows somethign like this
B P F I FP BP 2 M 3 1 I L
0 64 73 76 64 61 32 36 94 81 49 94 48
1 57 58 69 46 34 66 15 24 20 49 25 98
2 99 61 73 69 21 33 78 31 16 11 77 71
3 41 1 55 34 97 64 98 9 42 77 95 41
4 36 50 54 27 74 0 8 59 27 54 6 90
5 74 72 75 30 62 42 90 26 13 49 74 9
6 41 92 11 38 24 48 34 74 50 10 42 9
7 77 9 77 63 23 5 50 66 49 5 66 98
8 90 66 97 16 39 55 38 4 33 52 64 5
9 18 14 62 87 54 38 29 10 66 18 15 86
10 60 89 57 28 18 68 11 29 94 34 37 59
11 78 67 93 18 14 28 64 11 77 79 94 66
I want the rows and coloumns to be switched. Moreover, How do I make it for all 5 main lists?
This is how I want the output to look like with other coloumns also filled in.
B P F I FP BP 2 M 3 1 I L
0 64
1 73
1 76
2 64
3 61
4 32
5 36
6 94
7 81
8 49
9 94
10 48
However. df.transpose()
won't help.
Use the T attribute or the transpose() method to swap (= transpose) the rows and columns of pandas. DataFrame . Neither method changes the original object but returns a new object with the rows and columns swapped (= transposed object).
transpose() function transpose index and columns of the dataframe. It reflect the DataFrame over its main diagonal by writing rows as columns and vice-versa.
To interchange rows with columns, you can use the t() function. For example, if you have the matrix (or dataframe) mat you can transpose it by typing t(mat) . This will, as previously hinted, result in a new matrix that is obtained by exchanging the rows and columns.
You can use the following basic syntax to convert a pandas DataFrame from a wide format to a long format: df = pd. melt(df, id_vars='col1', value_vars=['col2', 'col3', ...]) In this scenario, col1 is the column we use as an identifier and col2, col3, etc.
This is what I came up with
data = [[[randrange(0,100) for j in range(0, 12)] for y in range(0, 12)] for x in range(0, 5)]
print data
df = pandas.DataFrame(data[0], columns=['B','P','F','I','FP','BP','2','M','3','1','I','L'])
print df
df1 = df.transpose()
df1.columns = ['B','P','F','I','FP','BP','2','M','3','1','I','L']
print df1
