下面的方法将用于合并两个字典。 defmerge_two_dicts(a, b): c = a.copy() # make a copy of a c.update(b) # modify keys and values of a with the ones from breturn ca = { 'x': 1, 'y': 2}b = { 'y': 3, 'z': 4}print(merge_two_dicts(a, b))# {'y': 3, 'x': ...
我们执行建议的函数var_names_make_unique(),通过将数字字符串附加到每个重复的索引元素(“1”、“2”等)来使变量名称唯一。 同样地,我们也可以使用obs_names_make_unique()来使obs(=细胞)唯一 代码语言:javascript 代码运行次数:0 运行 AI代码解释 adata.var_names_make_unique()adata.obs_names_make_unique(...

First make sure modifying is done on the actual memory not the view. For example, df.iloc[] returns the copy but df.iloc[].value returns the original df. lst = [1,2,3] for i, val in enumerate(lst): if i % 2 == 0: lst.pop(i) if in above scenario, the correct way is to...
