Questions to [David Rotermund](mailto:davrot@uni-bremen.de)
## Examples
### Input / Print
```python
a = input() # <- test
print(a) # -> test
```
### String to int
```python
a = int(5)
print(a) # -> 5
print(type(a)) # -> <class 'int'>
a = int(-5)
print(a) # -> -5
print(type(a)) # -> <class 'int'>
a = int("5")
print(a) # -> 5
print(type(a)) # -> <class 'int'>
a = int("-5")
print(a) # -> -5
print(type(a)) # -> <class 'int'>
a = int(" 5 ")
print(a) # -> 5
print(type(a)) # -> <class 'int'>
a = int("3.4") # ValueError: invalid literal for int() with base 10: '3.4'
a = int("Hello") # ValueError: invalid literal for int() with base 10: 'Hello'
```
### String to float
```python
a = float(5)
print(a) # -> 5.0
print(type(a)) # -> <class 'float'>
a = float(5.1)
print(a) # -> 5.1
print(type(a)) # -> <class 'float'>
a = float(-5.1)
print(a) # -> -5.1
print(type(a)) # -> <class 'float'>
a = float("5.1")
print(a) # -> 5.1
print(type(a)) # -> <class 'float'>
a = float("-5.1")
print(a) # -> -5.1
print(type(a)) # -> <class 'float'>
a = float(" 5.1 ")
print(a) # -> 5.1
print(type(a)) # -> <class 'float'>
a = float("Hello") # ValueError: could not convert string to float: 'Hello'
```
