I'm trying to do a for loop. Introduce a value (p) into an empty list. I want to do a kind of vector that save me all source values of the math operations.
lista=list()
for index in len(lista+1):
lista.append(p)
index=index+1
print lista
Thx for your help
If you just want to insert a value into an empty list it should look like this:
ps = [] # create the empty list
ps.append(p) # add the value p
or you could just do this which gives the same result ps = [p]
If you want to insert it n-times you can use a for loop like this:
ps = []
for i in range(n):
ps.append(p)
or just do this which gives the same result ps = n * [p]
you can try this:
lista = [i*i for i in range(N)]
print lista
or use:
for i in range(N)
lista.append(i*i)
print lista
You should be doing for index in range(len(lista) + 1): instead of for index in len(lista+1):
To simplify your code, you can also do:
lista = list()
[p] * (len(lista) + 1)
for index in range(len(lista)+1)?lista=list()
for index in range(len(lista)):
lista.insert(p)
index=index+1
print lista
lista.append(p).lista.extend(p * n).lista+1) and (2) trying to iterate over an int (len(lista+1)). Neither of these makes sense, and both result in errors.
