I have a list of strings. I now want to create a list for each string within my original list. I don't want to hard code in the new lists.
For example if my list is my_list = ['Paul', 'Ringo', 'John', 'George'] I want to create 4 new lists, one for each string (Paul = [ ] Ringo = [ ] etc). Any ideas? Thanks!
You cannot dynamically name variables on run time with Python. However, you could fill a dictionary where the keys are the items from the list and the values are an empty list. Like this:
my_list = ['Paul', 'Ringo', 'John', 'George']
my_dict = {}
for name in my_list:
my_dict[name] = []
print(my_dict)
# {'Paul': [], 'Ringo': [], 'John': [], 'George': []}
For bonus, you can use dictionary comprehension which is way shorter. Like this:
my_list = ['Paul', 'Ringo', 'John', 'George']
my_dict = {item:[] for item in my_list}
print(my_dict)
# {'Paul': [], 'Ringo': [], 'John': [], 'George': []}
This is a case to use a dictionary:
my_list = ['Paul', 'Ringo', 'John', 'George']
dict = {}
for beatles in my_list:
dict[beatles] = []
print(dict)
dict['Paul'].append('Yellow Submarine')
print(dict['Paul'])
my_list = ['Paul', 'Ringo', 'John', 'George']
b=[ (i+'=[]') for i in my_list]
for i in b:
exec(i)
print(Paul)
Use execute function to execute string statement as python statements
Above lines creates four list variables
