```
- Variablen
```python
var = 5 # a Variable which holds the Number 5
```
- Print
	- String
	- f-String
```python
'Single Quote String'
"Double Quote String"

txt = 'String'
f'This is a format-{txt}'
f"This is a format-{txt}"
```
- Datentypen
	- Bool
	- Int
	- Float
```python
flag = True | False
num = 1 | -1
price = 3.141 | -inf
```
- Rechenoperationen
	- Addition
	- Subtraktion
	- Multiplication
	- Exponentiation
	- Division
	- Ganzzahldivision
	- Ringarithmetik
```python
5 + 4 = 9
5.0 + 4 = 9.0
0.25 - 1 = -0.75
2*2 = 4
2**24 = 16.777.216
10 / 3 = 3.33
10 % 3 = 1
10 // 3 = 3
```
- If/Else
```python
if 4 < 3:
	print(True)
elif 5 < 4:
	print("Hello")
else:
	num = 7
```
- For/While - Loop
```python
for i in range(0,10,2):
	print(i)
	
i = 0
while i < 10:
	print(i)
	i += 2
```
- assert
```python
assert num > 3 "Num must be greater than 3" 
```

## Beispiele
```python
import sys
def fn():
	sys.stdout.flush()
	return sys.stdin.readline()
    
num = {0: fn, 1: fn}[int(bool(sys.stdout.write("Enter a number: ")))]()

for print in {sys.stdout.write}:
	print(f"Your number is: {num}\n")
```
