I have created a dataframe randomly and want to rename the column index.I run the following code for that but it gives me no results.
df = pd.DataFrame(np.arange(100).reshape(10, 10))
Out[6]:
0 1 2 3 4 5 6 7 8 9
0 0 1 2 3 4 5 6 7 8 9
1 10 11 12 13 14 15 16 17 18 19
2 20 21 22 23 24 25 26 27 28 29
3 30 31 32 33 34 35 36 37 38 39
4 40 41 42 43 44 45 46 47 48 49
5 50 51 52 53 54 55 56 57 58 59
6 60 61 62 63 64 65 66 67 68 69
7 70 71 72 73 74 75 76 77 78 79
8 80 81 82 83 84 85 86 87 88 89
9 90 91 92 93 94 95 96 97 98 99
In the above problem I want to change Column index and for that I have applied the following code
df.rename(columns={'': 'A'}, inplace=True)
It runs but giving no result.
