Program 31 -Break and Continue

# break – example<\/span><\/strong>
\nprint(“The break instruction:”)<\/span><\/strong>
\nfor i in range(1, 6):<\/span><\/strong>

\nbreak<\/span><\/strong>
\nprint(“Inside the loop.”, i)<\/span><\/strong>
\nprint(“Outside the loop.”)<\/span><\/strong><\/p>\n

# continue – example
\n<\/span>print(“\\nThe continue instruction:”)  #NOTE: Puts a space between<\/span><\/strong>

Program 32 – Kind of a Bubble Sort one Step at a Time
\n<\/strong><\/p>\n

largest_number = -99999999 # Initialize variable<\/span><\/strong>

Program 35 – Practice program for CONTINUE
\n<\/strong><\/p>\n

REDO LABS previous lab (3.1.2.10) AND previous lab (3.1.2.11)
\nI DO NOT GET CONTINUE AT ALL<\/p>\n

Program 36 -Import Sys and Exit and While

Program 37 -Temperature Conversion Program
