在这个问题中,给出了一个字符串,我们必须检查给定字符串中是否存在子字符串。
Step 1: input a string and a substring from the user and store it in separate variables. Step 2. Check if the substring is present in the string or not. To do this using find() in-built function. Step 3. Print the final result. Step 4. Exit.
def check(str1, sstr): if (str1.find(sstr) == -1): print(sstr,"IS NOT PRESENT IN THE GIVEN STRING") else: print(sstr,"IS PRESENT IN THE GIVEN STRING") # Driver code str1 = input("Enter the string ::>") sstr=input("Enter Substring ::>") check(str1, sstr)
输出结果
Enter the string ::> python program Enter Substring ::> program program IS PRESENT IN THE GIVEN STRING Enter the string ::> python program Enter Substring ::> programming programming IS NOT PRESENT IN THE GIVEN STRING
