This example demonstrates how to use the any and isalpha functions to check if a character string contains a letter from the alphabet.Let’s check our first character string my_string1:print(any(c.isalpha() for c in my_string1)) # Check if letters are contained in string # True...
\D Returns a match where the string DOES NOT contain digits "\D" Try it » \s Returns a match where the string contains a white space character "\s" Try it » \S Returns a match where the string DOES NOT contain a white space character "\S" Try it » \w Returns a match ...
To check if a key resides within the dictionary: if 'Helium' in elements: print('Helium is present') 5. Iterating Over Keys To iterate over the keys in the dictionary: for element in elements: print(element) # Prints each key 6. Iterating Over Values To traverse through the values in...

Any function that contains a yield statement returns a generator. Generators and iterators are interchangeable.def count(start, step): while True: yield start start += step >>> counter = count(10, 2) >>> next(counter), next(counter), next(counter) (10, 12, 14) Type...
The string is enclosed in double quotation marks if the string contains a single quotation mark and no double quotation marks. Otherwise, it’s enclosed in single quotation marks.The print() function produces more readable output by omitting the enclosing quotes and by printing escaped special ...
Finally, you use the precision option to display a floating-point number using different precisions. You use two, four, and eight digits after the decimal separator, respectively. Unfortunately, the modulo operator doesn’t support the string formatting mini-language, so if you use this tool to...
