adding data to a list in python

Question

I've started learning python just a few days back and am stuck with a problem.

If, list=['tuesday','wednesday','friday','sunday']

I'm trying to write a function so i could pass in a specific index number and a value to insert and rather than using list.insert(0,'monday') then list.insert(2,'thursday') and so on I could directly pass the indexes eg. ind = [0,2....] and values = ['monday','thursday'....] and get a result as list = ['monday', 'tuesday','wednesday', 'thursday', 'friday', 'saturday', 'sunday']

tried

list = ['tuesday','wednesday','friday','sunday']
indexes = [0,1,2,3]
values = ['monday','thursday','saturday']
for index, value in (indexes, values):
    result = list.insert(index, value)
print (result)

and many other things but failed...help would be appreciated

There you have the solution:

list = ['tuesday','wednesday','friday','sunday']
indexes = [0,3,5]
values = ['monday','thursday','saturday']

result = list
for index in range(len(indexes)):
    result.insert(indexes[index], values[index])

print (result)

Please take into account return is just for functions

Try this

days = ['tuesday','wednesday','friday','sunday']
indexes = [0,3,5]
values = ['monday','thursday','saturday']
for i in range(len(indexes)):
    days.insert(indexes[i], values[i])
return days

your code is similar to what I was trying and the output is ValueError Traceback (most recent call last) <ipython-input-1-8769b70b69ea> in <module> 2 indexes = [0,1,2,3] 3 values = ['monday','thursday','saturday'] ----> 4 for index, value in (indexes, values): 5 days.insert(index, value) 6 return days ValueError: too many values to unpack (expected 2)

Did you change the variable list to days as mentioned

mentalist Over a year ago

be it days or list name really does not matter....but after you edits to the program, it would have worked if we gave print(days) instead of return.... and if your indexing was right....with your indexing the result would be ['monday', 'thursday', 'tuesday', 'wednesday', 'friday', 'saturday', 'sunday'] answer by @Eugenio is perfect ....cheers buddy
