code not working

Question

Hello
I am continuing to learn with "crash course in python"
I am at the section on dictionary and how to put dictionary into list, and iterate through them.
I started by creating a list and dictionary, and wrote a code to insert the dictionary in the list, worked fine.
Then I tried to modify the value of one key, in some of the dictionary.
dic = {
'a' : 1,
'b' : 2,
'c' : 4,
'd' : 5,

}
list1 = ['f','e','c','n']
print(list1)
print(len(list1))
x = 0
while x < 7:
if x <= len(list1) - 1:
list1[x] = dic
x += 1
else:
list1.append('vv')
x +=1
print(list1)
for dic in list1[:2]:
dic['c'] = 'wistiti'
print(list1)

I wrote it exactly like in the book but does not work. With this version the key 'c' is changed to the specify value, in EVERY dictionary in my list. And if I write
list1[1] list1[:] I get this error message

File "c:....../Crash course/dictionaryloop.py", line 21, in <module>
dic['c'] = 'wistiti'
TypeError: 'str' object does not support item assignment

Any input on what I am doing wrong?

Answer 6

Hello

After the first part of the code, the list list1 has four dictionary in position, 0, 1 , 2 and 3.
I want to change the value of the key 'c' to 'wistitié , but only for the dictionary in position 0 and 1 ( hence I wrote :2 ), but the value is changed in all the dictionaries.
