Python’s syntax is similar in some respects to other popular programming languages. But when experienced programmers first encounter Python they’re usually struck by the lack of brackets and braces to denote conditional logic. Python instead uses whitespace to signify those elements. This notation system lends itself to extremely clean code. But it can take a […]
About the Author: Jack Sanderson is a software engineer with a degree from a leading US technical university and experience at two machine learning startups. His passions include streamlining the repetitive aspects of database engineering and IT operations, where he uses his expertise in Python and DevOps to simplify and scale production data pipelines. He's a regular speaker at Python user conferences, championing the growth of the language within the data engineering community. When he's not debugging code or explaining some weird Python error to one of his teammates, he can be found volunteering at the local pet shelter or mountain biking in foreign countries. He asks that you always spay or neuter your pet and of course, never let errors pass silently (unless explicitly silenced).
How To Fix the Python Error: Indentationerror: Expected an Indented Block After ‘For’ Statement
Python distinguishes itself from other programming languages in a variety of different ways. But there are few elements as visually distinct as Python’s use of whitespace. Most other programming languages use specific characters to open and close code blocks or elements of conditional logic. But Python’s syntax replaces those markers with whitespace. The end effect […]
How To Fix the Python Error: Indentationerror: Expected an Indented Block After ‘With’ Statement
Indentation as an indication of programming logic is one of Python’s most well-known features. But it’s often one of the more difficult aspects of the language for people to get used to when they first start writing Python code. The error messages associated with indentation issues can also be confusing. For example, the “indentationerror: expected […]
How To Use %s in Python To Format Strings
Variable manipulation is one of the best things about Python. Most programming languages put heavy restrictions on what you can do with any given variable type. Python obviously does have some limitations. But you can generally format your data in a variety of powerful ways with an ease that isn’t found in most other languages. […]
How To Convert Byte Like Object To String
Data types and variables are some of the Python language’s greatest strengths. The language typically makes it easy to manipulate data without needing to worry too much about specific typing. However, there are some instances where similar data types are fundamentally incompatible with each other. One of the best example of this dichotomy is Python’s […]
How To Fix the Python Error: Typeerror: A Bytes-Like Object Is Required, Not ‘Str’
Variables in Python are easy to learn but often have unexpected quirks. This makes typeerrors an especially common issue when exploring new areas of the language. But if you’ve found yourself confronted with a “typeerror: a bytes-like object is required, not ‘str’” error then you’ll be happy to know it’s generally fairly easy to fix. […]
How To Fix the Python Error: Cannot Use a String Pattern on a Bytes-Like Object
Python’s interpreter is far more lenient with variable handling than most other programming languages. However, you’ll still run into situations where variable types cause conflicts with each other. This is especially true of bytes-like objects and stings. The cannot use a string pattern on a bytes-like object error is a perfect example of this phenomenon. […]
Python Error: Int() Argument Must Be a String, a Bytes-Like Object or a Number, Not ‘List’
One of Python’s greatest strengths comes from its various data types. The language provides a considerable amount of flexibility in using or even converting data from one format to another. However, if you’ve received an error message reading ‘ int argument must be a string a bytes-like object or a number not list ‘ then […]
How To Fix the Python Error: Typeerror: Int() Argument Must Be a String, a Bytes-Like Object or a Number, Not ‘Nonetype’
The Python language is well known for its data types and flexibility in variable manipulation. However, there are instances where Python’s extensive capabilities there can create some confusing errors. And that’s exactly the case with a ” typeerror: int() argument must be a string, a bytes-like object or a number, not ‘nonetype’ ” error. But […]
How To Fix the Python Error: TypeError: A Bytes-Like Object Is Required, Not ‘Str’ Socket
One of the great things about Python is that it can vastly simplify normally difficult feats of programming. Creating networked nodes, communicating over a client/server model, and a variety of other normally difficult tasks can be accomplished with just a few blocks of code. However, new functionality opens up the possibility of new errors. And […]
