Split the definition of a long string over multiple lines

You can split a string over multiple lines using the line continuation character “” or using parentheses “( )”.

Example:

Python
long_string = "This is a very long string that needs to be split \
over multiple lines for better readability."

# or 

long_string = ("This is a very long string that "
               "needs to be split over multiple lines "
               "for better readability.")

Using triple quote

You can use triple quotes """ or ''' to define a string that spans multiple lines. The line breaks within the string will be included in the final string value.

Example:

Python
long_string = """This is a very long string that
needs to be split over multiple lines for
better readability."""

Merge several ‘strings’

You can merge several strings into one long string in Python using string concatenation or string formatting.

Here’s an example of using string concatenation to merge three strings into one:

Python
string1 = 'Hello'
string2 = ', '
string3 = 'world!'
merged_string = string1 + string2 + string3
print(merged_string) 

Output:

Hello, world!

In this example, we have three strings ‘string1‘, ‘string2‘, and ‘string3‘. We use the ‘+‘ operator to concatenate the three strings into ‘merged_string‘. We then print ‘merged_string‘ to the console to verify that the three strings have been merged.

Another way to merge strings is to use string formatting. Here’s an example:

Python
string1 = 'Hello'
string2 = 'world!'
merged_string = '{} {}.'.format(string1, string2)
print(merged_string)  

Output:

Hello, world!

In this example, we use string formatting to merge the two strings ‘string1' and ‘string2‘ into ‘merged_string‘. The curly braces {} serve as placeholders for the values that will be inserted into the string. We then use the ‘format()‘ method to insert the values of ‘string1‘ and ‘string2‘ into the placeholders. The result is a merged string with the two strings separated by a space and a period.

There are other methods to merge strings in Python, such as using the ‘join()‘ method or f-strings, but string concatenation and string formatting are two of the most common ways to merge strings into one long string.
