Add one Python string to another
By adding strings in python we just concatenate them to get a new string. This is useful in many scenarios like text analytics etc. Below are the two approaches we consider for this task.
Using += Operator
The + operator can be used for strings in a similar was as it is for numbers. The only difference being, in case of strings the concatenation happens and not a numeric addition.
Example
s1 = "What a beautiful "
s2 = "flower "
print("Given string s1 : " + str(s1))
print("Given string s2 : " + str(s2))
#Using += operator
res1 = s1+s2
print("result after adding one string to another is : ", res1)
# Treating numbers as strings
s3 = '54'
s4 = '02'
print("Given string s1 : " + str(s3))
print("Given string s2 : " + str(s4))
res2 = s3+s4
print("result after adding one string to another is : ", res2)Output
Running the above code gives us the following result −
Given string s1 : What a beautiful Given string s2 : flower result after adding one string to another is : What a beautiful flower Given string s1 : 54 Given string s2 : 02 result after adding one string to another is : 5402
Using join
We can use the join() in a similar manner as the plus operator above. We can join any number of strings using this method. The result will be same as the plus operator.
Example
s1 = "What a beautiful "
s2 = "flower "
print("Given string s1 : " + str(s1))
print("Given string s2 : " + str(s2))
print("result after adding one string to another is : "," ".join((s1,s2)))
# Treating numbers as strings
s3 = '54'
s4 = '02'
print("Given string s1 : " + str(s3))
print("Given string s2 : " + str(s4))
print("result after adding one string to another is : ","".join((s3,s4)))Output
Running the above code gives us the following result −
Given string s1 : What a beautiful Given string s2 : flower result after adding one string to another is : What a beautiful flower Given string s1 : 54 Given string s2 : 02 result after adding one string to another is : 5402
