首先可以用findDuplicates()方法来查找重复的曲目，如下所示：def findDuplicates(fileName): print('Finding duplicate tracks in %s...' % fileName) # read in a playlist① plist = plistlib.readPlist(fileName) # get the tracks from the Tracks dictionary② tracks = plist['Tra...
samples = secure_random.sample(my_list, num_samples) print(samples) # [ e , d ] this will have any 2 random values 19. 数字化 以下代码将一个整数转换为数字列表。 num = 123456 # using map list_of_digits = list(map(int, str(num))) print(list_of_digits) # [1, 2, 3, 4, 5,...
It is filled # only in case of collision on the small hash (contains at least two # elements) duplicates = {} for f in files: # small hash to be fast check = Checksum(f, first_block = True, check_type = 'sha1') if(not d.has_key(check)): # d[check] is a list of files...
my_list = [0]*n # n denotes the length of the required list # [0, 0, 0, 0] 5. 列表解析 在其他列表的基础上,列表解析为创建列表提供一种优雅的方式。 以下代码通过将旧列表的每个对象乘两次,创建一个新的列表。 # Multiplying each element in a list by 2 ...
Finding the location of an item For lists, there's also the index method that can sometimes be useful if you want to know where a certain element is in the list: [1,2,3].index(2) # => 1 [1,2,3].index(4) # => ValueError However, note that if you have duplicates, .index...
# Finding duplicate values by calling the find_duplicate_values function duplicates = find_duplicate_values(original_dict) # Printing the duplicate values print("Duplicate Values:", duplicates) Lookat the duplicate value in the dictionary; theoriginal_dictis5for the different keys. ...

# Finding duplicates in census_B census_B_duplicates = census_B[census_B.index.isin(duplicate_rows)] # Finding new rows in census_B census_B_new = census_B[~census_B.index.isin(duplicate_rows)] # Link the DataFrames! full_census = census_A.append(census_B_new) ...
First, for list A, we find the mode, which is the element with the highest frequency in the list.Then, we create a set from the list to remove duplicates, and then we use the max() function with the key argument set to A.count to identify the element with the maximum count in ...
