Function to update existing cell type annotations

[Zethson]

new_cell_types = {
    "37": "Lyg6+ Neutrophils",
    "13": "Retnlg+ Neutrophils",
    "29": "Ccl3+ Neutrophils",
    "34": "Basophils"
}
new_obs = adata.obs.copy()
new_obs = new_obs.astype({"cell_type": "str"})
for cluster_number, new_celltype in new_cell_types.items():
    new_obs.loc[new_obs['leiden_1_5'] == cluster_number, "cell_type"] = new_celltype
adata.obs = new_obs

Could parameterize something like this
