Trích xuất chuỗi con từ chuỗi Python

Cho một chuỗi và hai chuỗi con, hãy viết chương trình Python để trích xuất chuỗi giữa hai chuỗi con tìm được.  

Thí dụ

Đầu vào. test_str = “Gfg là tốt nhất cho chuyên viên máy tính và CS”, sub1 = “là”, sub2 = “và”

đầu ra. tốt nhất cho chuyên viên máy tính

Giải trình. tốt nhất cho chuyên viên máy tính là giữa là và 'và'

Đầu vào. test_str = “Gfg là tốt nhất cho chuyên viên máy tính và CS”, sub1 = “dành cho”, sub2 = “và”

đầu ra. chuyên viên máy tính

Giải trình. chuyên viên máy tính là giữa cho và 'và'

Sử dụng vòng lặp index[] + để trích xuất chuỗi giữa hai chuỗi con

Trong trường hợp này, chúng tôi lấy các chỉ số của cả hai chuỗi con bằng cách sử dụng chỉ mục [], sau đó một vòng lặp được sử dụng để lặp lại trong chỉ mục để tìm chuỗi cần thiết giữa chúng
