- in Mongo DB We want to add some students to our collection, but this time, we define the value for the _id field. (If the _id is not defined in your document, it will be added automatically.) _id: 1001 first_name: Sarah last_name: Stone email: s_stone@email.com city: Toronto status: full-time gpa: 3.4 program: CPA _id: 1002 first_name: Jack last_name: Adam email: j_adam@email.com city: North York status: part-time gpa: 3.6 program: CPA To add these students, we want to store these documents into a variable first. Define a variable named starray and add these two document to the variable. (You are storing more than one document so you need to define an array.) write the command to define the array: Now, use the starray array to insert the documents to your collection student. Write your insert statement:why when add new index in python data frame its make all columns nan and when I remove it not make column nan ? ex ) I create data frame with index [f1 t0 f30] when I create to f9 its ok all but when add f10 make all before data null?In BASH, how do you make it so your script can deal with both absolute and relative paths?
