⭐How to merge string in Python?

We can perform string concatenation using following ways:

1. Using + operator.
2. Using join() method.
3. Using % operator.
4. Using format() function.
5. Using f-string (Literal String Interpolation)

⭐Python String strip() Method

Remove spaces at the beginning and at the end of the string:

txt = "     banana     "x = txt.strip()print("of all fruits", x, "is my favorite")

banana

txt = ",,,,,rrttgg.....banana....rrr"

x = txt.strip(",.grt")

print(x)

banana

 

⭐Python map() Function

The map() function executes a specified function for each item in an iterable. The item is sent to the function as a parameter.

 

map(function, iterables)

 

Parameter Description

function	Required. The function to execute for each item
iterable	Required. A sequence, collection or an iterator object. You can send as many iterables as you like, just make sure the function has one parameter for each iterable.

 

Example 1

def myfunc(n):
  return len(n)

x = map(myfunc, ('apple', 'banana', 'cherry'))

<map object at 0x056D44F0>

[5, 6, 6]

 

Example 2

def myfunc(a, b):
  return a + b

x = map(myfunc, ('apple', 'banana', 'cherry'), ('orange', 'lemon', 'pineapple'))

<map object at 0x034244F0>
['appleorange', 'bananalemon', 'cherrypineapple']

 

 

⭐Python String split() Method

Split a string into a list where each word is a list item:

 

string.split(separator, maxsplit)

 

Parameter Description

separator	Optional. Specifies the separator to use when splitting the string. By default any whitespace is a separator
maxsplit	Optional. Specifies how many splits o do. Default value is -1, which is "all occurrences"

 

Example 1: Split the string, using comma, followed by a space, as a separator

txt = "welcome to the jungle"

x = txt.split()

print(x)

['welcome', 'to', 'the', 'jungle']
