Which method would you use to determine whether a substring is the suffix of a string?

In this tutorial, we will learn about the Python String endswith() method with the help of examples.

The endswith() method returns True if a string ends with the specified suffix. If not, it returns False.

Example

message = 'Python is fun'

# check if the message ends with fun print(message.endswith('fun'))

# Output: True


Syntax of String endswith()

The syntax of endswith() is:

str.endswith(suffix[, start[, end]])

endswith() Parameters

The endswith() takes three parameters:

  • suffix - String or tuple of suffixes to be checked
  • start (optional) - Beginning position where suffix is to be checked within the string.
  • end (optional) - Ending position where suffix is to be checked within the string.

Return Value from endswith()

The endswith() method returns a boolean.

  • It returns True if a string ends with the specified suffix.
  • It returns False if a string doesn't end with the specified suffix.

Example 1: endswith() Without start and end Parameters

text = "Python is easy to learn."

result = text.endswith('to learn')

# returns False print(result)

result = text.endswith('to learn.')

# returns True print(result)

result = text.endswith('Python is easy to learn.')

# returns True print(result)

Output

False
True
True

Example 2: endswith() With start and end Parameters

text = "Python programming is easy to learn."

# start parameter: 7
# "programming is easy to learn." string is searched

result = text.endswith('learn.', 7)

print(result) # Both start and end is provided # start: 7, end: 26 # "programming is easy" string is searched

result = text.endswith('is', 7, 26)

# Returns False print(result)

result = text.endswith('easy', 7, 26)

# returns True print(result)

Output

True
False
True

Passing Tuple to endswith()

It's possible to pass a tuple suffix to the endswith() method in Python.

If the string ends with any item of the tuple, endswith() returns True. If not, it returns False


Example 3: endswith() With Tuple Suffix

text = "programming is easy"

result = text.endswith(('programming', 'python'))

# prints False print(result)

result = text.endswith(('python', 'easy', 'java'))

#prints True print(result) # With start and end parameter # 'programming is' string is checked

result = text.endswith(('is', 'an'), 0, 14)

# prints True print(result)

Output

False
True
True

If you need to check if a string starts with the specified prefix, you can use startswith() method in Python.

Find If String Is Substring Of Another With Code Examples

In this session, we will try our hand at solving the Find If String Is Substring Of Another puzzle by using the computer language. The following piece of code will demonstrate this point.

#is target in base?
def findSubstring(base, target):
   match = ""
   for x in range(0, len(base)):
       substring = base[0:len(base)-x]
       if substring == target:
           print("there is a match")
           match = substring
   if match == "":
     return ""
   else:
     return match
print(findSubstring("aaaaaaa", "aaa"))

By examining a variety of different samples, we were able to resolve the issue with the Find If String Is Substring Of Another directive that was included.

How do you find if a string is a substring of another string?

You can use contains(), indexOf() and lastIndexOf() method to check if one String contains another String in Java or not. If a String contains another String then it's known as a substring. The indexOf() method accepts a String and returns the starting position of the string if it exists, otherwise, it will return -1.

How do you find if a given string is substring of another in C++?

Check if a string contains a sub-string in C++ This find() method returns the first location where the string is found. Here we are using this find() function multiple times to get all of the matches. If the item is found, this function returns the position. But if it is not found, it will return string::npos.30-Jul-2019

How do you check if a string is a substring of another JS?

To check if a substring is contained in a JavaScript string: Call the indexOf method on the string, passing it the substring as a parameter - string. indexOf(substring) Conditionally check if the returned value is not equal to -1. If the returned value is not equal to -1 , the string contains the substring.25-Jul-2022

How do you check if a string contains another substring in C?

How can I compare two strings in C++?

In order to compare two strings, we can use String's strcmp() function. The strcmp() function is a C library function used to compare two strings in a lexicographical manner. The function returns 0 if both the strings are equal or the same.03-Aug-2022

How do I find a particular substring in a string in Java?

To locate a substring in a string, use the indexOf() method. Let's say the following is our string. String str = "testdemo"; Find a substring 'demo' in a string and get the index.27-Jun-2020

Which method would you use to determine whether a substring is the suffix of a string?

The endsWith() method determines whether a string ends with the characters of a specified string, returning true or false as appropriate.13-Sept-2022

Is substring in Java?

The substring() method returns a substring from the given string. The substring begins with the character at the startIndex and extends to the character at index endIndex - 1 . If the endIndex is not passed, the substring begins with the character at the specified index and extends to the end of the string.

Which method would you use to determine whether a certain substring is the prefix of a string?

The startsWith() method determines whether a string begins with the characters of a specified string, returning true or false as appropriate.

How do you find a substring in a string?

You first check to see if a string contains a substring, and then you can use find() to find the position of the substring. That way, you know for sure that the substring is present. So, use find() to find the index position of a substring inside a string and not to look if the substring is present in the string.

Which method could be used to strip specific characters from the end of a string?

TrimEnd. The String. TrimEnd method removes characters from the end of a string, creating a new string object. An array of characters is passed to this method to specify the characters to be removed.
