String in Python has built-in functions for almost every action to be performed on a string. Python String startswith() function checks for the specific prefix in a string and returns True else False.

Key Points:

• Return Type: Boolean i.e. True or False
• Parametric Values: There are 3 parameters: Prefix, Start, End

Python String startswith() Syntax

str_name.startswith()

str_name here refers to the string in which prefix is to be checked and strartwith() is an inbuilt function.

String startswith() Examples

Example 1:

text_string = "Engineering and Management are altogether diferent verticals."

resultant = text_string.startswith('Engineering')

print(resultant)

resultant = text_string.startswith('Management ')

print(resultant)

Output :

Example 2:

text_string = "Engineering and Management are altogether different verticals."

resultant = text_string.startswith('Engineering',0)

print(resultant)

resultant = text_string.startswith('Management',16,60)

print(resultant)

Output:

Example 3:

str = "Engineering Discipline"

string=str.startswith("Discipline")

print (string)

Output:

False
