What does '\' mean when declaring a variable?

While I was searching code from the internet about YouTube data analysis, I found code like this:

df_rgb2['total_sign_comment_ratio'] = df_rgb2['total_number_of_sign'] / df_rgb2['comment_count']

total_sign_comment_ratio_max = df_rgb2['total_sign_comment_ratio'].replace([np.inf, -np.inf], 0).max()

df_rgb2['total_sign_comment_ratio'] = \

df_rgb2['total_sign_comment_ratio'].replace([np.inf, -np.inf], total_sign_comment_ratio_max*1.5)

and I was wondering why the analyst used the expression:

df_rgb2['total_sign_comment_ratio'] = \

because whether I apply that code or not, the result is same.

I tried to find the meaning of '\' but all I have got is how to use '\' when printing out the result.

Solution

  • \ is usually used to make a piece of code go on onto multiple lines. If you where to just press enter and continue to write code a line below for example declaring a variable, it would count as an error.

    You use this when you need to tidy up code or when your working window is too small for some reason.
