Pandas Concatenate DataFrames
df1: 
        Column 1  Column 2  Column 3
Row 1         1         2         3
Row 2         4         5         6
Row 3         7         8         9
df2: 
        Column 4  Column 5
Row 1        10        11
Row 2        12        13
Row 3        14        15
df3 after concatenation: 
        Column 1  Column 2  Column 3  Column 4  Column 5
Row 1         1         2         3        10        11
Row 2         4         5         6        12        13
Row 3         7         8         9        14        15

Here, we are concatenating two DataFrames along the columns. So, the axis parameter in the pandas.concat() function is 1.
