I want to input a large number by scientific notation, for example of distance to sun.
distance = float(input("distance to sun?:"))
I tried to enter 1.471*10**11 and 1.471e11, but both said "could not convert string to float"
Do I have to type the multiple "0"? Thanks for answering in advance.

I am new to machine learning. I am trying to learn feature selection from this link. Here they have a line of code which is given below
search = GridSearchCV(pipeline, grid, scoring='neg_mean_squared_error', n_jobs=-1, cv=cv)
But whenever I try to run this code I get the error
I cannot find where to import neg_mean_squared_error from. I am not sure where I should write the function myself or not. The tutorial isn't clear on this issue.
It is just a typo.
You need
neg_mean_absolute_error
You typed
neg_mean_absolure_error
using an r instead of t

I am struggling with an excel formula with multiple IF AND conditions. maybe you can help me. Here is an explanation of what I want to achieve:
List different prices if TWO conditions are met.
If A1=Ferrari AND B1=red, price=500; IF A1=Ferrari AND B1=gold, price=550; IF A1=Toyota AND B1=red, price=100, IF A1=Toyota and color=gold, price=110, else leave cell blank´
I hope you understand what I want to achieve and can help me.
This is what I tried but it gives me an error. I am using google sheets by the way.
=IF(AND(I27="ferrari"; K27="red")Variables!$R$1;IF(AND(I27="ferrari"; K27="gold")Variables!$R$2;IF(AND(I27="toyota"; K27="red")Variables!$V$3;IF(AND(I27="toyota"; K27="gold")Variables!$V$4;""))))
I think you've got your semi colons and commas mixed up! Try this...
=IF(AND(I27="ferrari",K27="red"),Variables!$R$1,IF(AND(I27="ferrari",K27="gold"),Variables!$R$2,IF(AND(I27="toyota",K27="red"),Variables!$V$3,IF(AND(I27="toyota",K27="gold"),Variables!$V$4,""))))
You were also missing commas after some of your closing parentheses.

I'm pasting in the formula:
=RANDBETWEEN(DATE(2014, 1, 1),DATE(2015, 1, 1))
which is mentioned in several tutorials but getting the Excel "error with function message". I'm in Ireland which is a different format but either way it doesn't work.
Anything else I have to do to generate random dates?
Try :
=RANDBETWEEN(41640,42005)
And format as date.
For some countries:
=RANDBETWEEN(41640;42005)
And format as date.
And if the 2nd works maybe just:
=RANDBETWEEN(DATE(2014; 1; 1);DATE(2015; 1; 1))
