This course is an invaluable resource for anyone who wants to learn the correct Pythonian way of writing highly performant code that is easy to maintain and grow.

The course is divided into six chapters: documentation tips, data types/data structures tips, safety tips, performance tips, function design tips, and general tips. Throughout each chapter, you will get hands-on experience working with real Python code to help ingrain each concept.

By the end, you will know how to make your programs correct, safe, fast, and easy to maintain.

Pythonic Programming Tips for Software Engineers

We can enclose string literals in Python in four types of quotation marks.
* `' '`
* `" "`
* `''' '''`
* `""" """`


Single and double quotation marks define single-line strings. Line breaks aren’t allowed within:
```python
'Mary had a little lamb'
"Mary had a little lamb"
``` 

There’s no difference between single and double quotation marks in Python. This is unlike C, C++, and Java, where single marks are used for individual characters and double marks are used for strings, or PHP, where double-quoted strings are interpreted but single-quoted strings are not. Choosing single or double quotation marks is a matter of personal preference. 
Triple-single and triple-double quotation marks define multiline strings. They can include literal line breaks.

print('''Mary had a little lamb''')
print("""Mary had a little lamb""")

# We can print in multiple lines using triple-quotes

print('''Mary had a 
little lamb''')

Again, there’s no difference between triple-single and triple-double quotation marks. We can use whatever we like. but we have to try to be consistent.

# Keep letter case consistent
Any Python identifier must start with a Latin letter (“a” through “z” or “A” through “Z”) or an underscore and contain only Latin letters, decimal digits (“0” through “9”), or underscores. Identifiers should be short (to facilitate typing) and descriptive.

Additionally, use all uppercase letters for constants, though Python doesn’t have constants as such. We can change the value of any variable. When we spell an identifier in all capital letters, however, we suggest that the variable’s value shouldn’t be changed. Here’s a constant:
```python
PI = 3.14159 # But please use math.pi instead!
```
Use identifiers in lowercase, connected with underscores, if necessary, or mixedCase identifiers for variables, functions, and modules. Here are variable, function, and module identifiers:
