Parsing dict in Python

I have this dictionary, with some code to print from it:

fichiers_dict= {
    'sample1':{'libelle':'sample1.csv','server':'10.21.11.41'},
    'sample2':{'libelle':'sample2.csv','server':'192.168.1.40'},
    'sample3':{'libelle':'sample3.csv','server':'10.21.7.251'},
    'sample4':{'libelle':'sample4.csv','server':'10.21.12.200'} 
    }

 for serveurs in fichiers_dict:
    for fichier in fichiers_dict[serveurs]:
        print(fichiers_dict[serveurs][fichier]['libelle'])

When I run this, I get the following error:

TypeError: string indices must be integers, not str

What is wrong with the code?

If you want to print values with Key - 'libelle'

fichiers_dict= {
    'sample1':{'libelle':'sample1.csv','server':'10.21.11.41'},
    'sample2':{'libelle':'sample2.csv','server':'192.168.1.40'},
    'sample3':{'libelle':'sample3.csv','server':'10.21.7.251'},
    'sample4':{'libelle':'sample4.csv','server':'10.21.12.200'} 
    }

for key, value in fichiers_dict.items():
    print(value['libelle'])

for serveurs in fichiers_dict: # keys of fichiers_dict
    for fichier in fichiers_dict[serveurs]: # keys of fichiers_dict[serveurs]
        print(fichiers_dict[serveurs][fichier]['libelle']) # key(string)['libelle'] -> wrong

As I added in comments, when you iterate directly on dict, its the keys getting iterated. So fichiers_dict[serveurs][fichier] is the key libelle.

If you again to sub-index of the string libelle, it cannot be a string index, but only integer. 

for serveurs in fichiers_dict.values():
    print(serveurs['libelle'])

should be enough.
