for loop and if translate from R in Python

[Joey21]

Hi everyone,

i have a new work in data science.
My problem is that i always code in R and in python i have no good experience

1)
my code in R

for(i in 1:length(l)) X[,i] = MF[[i]](x)

in Python

for i in range(1,1+l.length()):
X[:,i]= MF[i](x)

i really don't know if it is right

2)
code in R

if(is.na(sv[1])) l = rep(0,length(V)) else l = sv[-1]

Python
this is very confusing for me i have noooo ideas
