3.3.5.1. Exercise: Strings#

For these two variables:

force = 150
moment = 34

Create a code that creates the variable str in such a way that:

print(str)

gives:

a)

I won't have difficulty solving this problem.

b)

Centre of mass of the "arm + forearm" segment.

c) (use the force variable)

Measured force: 150 N

d) (use the force and moment variables)

Measured force: 150 N
Measured moment: 34 Nm

e)

I received this strange message:
"ValueError('C:\temp unfound')"

f) (use the force and moment variables, and limit the width of your code lines to 80 characters)

We calculated a total force of 150 newton, while the calculated moment was 34 newton-meter.

# a)

str = "I won't have difficulty solving this problem."
print(str)

# b)

str = 'Centre of mass of the "arm + forearm" segment.'
print(str)

# c)

str = f"Measured force: {force} N"
print(str)

# d)

str = f"Measured force: {force} N\nMeasured moment: {moment} Nm"
print(str)

# e) (some examples):

str = "I received this strange message:\n\"ValueError('C:\\temp unfound')\""

str = 'I received this strange message:\n"ValueError(\'C:\\temp unfound\')"'

str = '''I received this strange message:
"ValueError('C:\\temp unfound')"'''

print(str)

# f) 

str = (
    f"We calculated a total force of {force} newton, "
    f"while the calculated moment was {moment} newton-meter."
)
print(str)
