concatenate python

# theres a lot of ways to concatenate in python
# here are all examples that i know:

world = 'World!'
number = '69'

a = 'Hello ' + ' ' + world + ' ' + number
b = 'Hello {} {}'.format(world, number)
c = f'Hello {world} {number}'  # most easy / beginner friendly
d = 'Hello %s %s', % (world, number)
e = 'Hello', world, number

# all of these will print "Hello World! 69"
print(a)
print(b)
print(c)
print(d)
print(e)

python concatenation

#// required library
import numpy as npy

#// define 3 (1D) numpy arrays
arr1 = npy.array([10, 20, 30])
arr2 = npy.array([40, 50, 60])
arr3 = npy.array([70, 80, 90])

arrCon = npy.concatenate([arr1, arr2, arr3])
print(arrCon)

#// concatenation can also happen with 2D arrays
arr1_2d = npy.array([
  [10, 20, 30],
  [40, 50, 60]
])
arr2_2d = npy.array([
  [11, 22, 33],
  [44, 55, 66]
])

arr_2dCon = npy.concatenate([arr1_2d, arr2_2d])
print(arr_2dCon)

python merge strings

my_list = ['a', 'b', 'c', 'd']
my_string = ','.join(my_list)
# Output = 'a,b,c,d'

python concatenate strings

x = ‘apples’
y = ‘lemons’
z = “In the basket are %s and %s” % (x,y)

string concatenation in python

x="String"
y="Python"
d="+"
c = "We can concatenation " + y + x + "with" + d + "Operator"
print(c)

concatenating strings in python

# concatenating strings just means combining strings together
# it is used to add one string to the end of another
# below are two exmaples of how concatenation can be used 
# to output 'Hello World':

# example 1:
hello_world = "Hello" + " World"
print(hello_world)

>>> Hello World

# example 2:
hello = "Hello"
print(hello + " World")

>>> Hello World

how to concatenate two strings in python

# use {}, where u want to place integer, or any other datatype.
# Use .formate at the end of string, 
# and finally place data variable in parentheses  
a = 123.1133
b = "Username"
c = True
print("a = {}".format(a))
print("b = {}".format(b))
print("c = {}".format(c))

#
# This code snippet takes a string input and append suffixes based on a number of conditions
# Condtion:
#    1 if the lenght of the string is grater than 3 characters and is not already
#       ended with "ing" then add suffix "ing"
#    2 else if the lenght of the string is grater than 3 then add suffix "ly"
#
# The code snippet can be improved to include more business conditions.

python string: string concatenation

# Хоёр мөрийн агуулгыг нэг мөр болгон нэгтгэхийн тулд Python нь + операторыг өгдөг. 
# Мөрүүдийг холбох энэ процессыг холболт гэж нэрлэдэг.

x = 'One fish, '
y = 'two fish.'
 
z = x + y
 
print(z)
# Output: One fish, two fish.
